Dream

http://en.wikipedia.org/wiki/Dream A <a href="http://sw.opencyc.org/concept/Mx4r2ExPHjoZQdeSlbULcz8CcA" class="cyc_term">Nightmare</a> is a scary or otherwise negative <a href="http://sw.opencyc.org/concept/Mx4rvVjNaJwpEbGdrcN5Y29ycA" class="cyc_term">Dream</a> Nightmare nightmare type of stuff A collection of collections. Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a> is a collection that is stuff-like in at least one respect. A collection <code>COL</code> is stuff-like just in case there is some sense of 'part' according to which every part of an instance of <code>COL</code> is itself an instance of <code>COL</code>. More precisely, for a collection to be an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a> it is sufficient that there be some spec-pred <code>PARTPRED</code> of <a href="http://sw.opencyc.org/concept/Mx4rvVj7bpwpEbGdrcN5Y29ycA" class="cyc_term">parts</a> (that is, some predicate <code>PARTPRED</code> for which<code> (<a href="http://sw.opencyc.org/concept/Mx4rvVtJUZwpEbGdrcN5Y29ycA" class="cyc_term">genlPreds</a> PARTPRED <a href="http://sw.opencyc.org/concept/Mx4rvVj7bpwpEbGdrcN5Y29ycA" class="cyc_term">parts</a>)</code> holds), such that if <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJECT1 COL)</code> and <code>(PARTPRED OBJECT1 OBJECT2)</code>, then <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJECT2 COL)</code>. Here are two examples. Consider <a href="http://sw.opencyc.org/concept/Mx4rvVi3c5wpEbGdrcN5Y29ycA" class="cyc_term">Breathing</a>. Take an instance of that, say a ten minute long period in which a person is breathing. Imagine some two minute snippet of that, one of its <a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> (a spec-pred of <a href="http://sw.opencyc.org/concept/Mx4rvVj7bpwpEbGdrcN5Y29ycA" class="cyc_term">parts</a>). That, too, is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVi3c5wpEbGdrcN5Y29ycA" class="cyc_term">Breathing</a>. So <a href="http://sw.opencyc.org/concept/Mx4rvVi3c5wpEbGdrcN5Y29ycA" class="cyc_term">Breathing</a> is a <a href="http://sw.opencyc.org/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a>, since all <a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> of an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVi3c5wpEbGdrcN5Y29ycA" class="cyc_term">Breathing</a> are also instances of <a href="http://sw.opencyc.org/concept/Mx4rvVi3c5wpEbGdrcN5Y29ycA" class="cyc_term">Breathing</a>. Consider <a href="http://sw.opencyc.org/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a>. Take any instance of <a href="http://sw.opencyc.org/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a> -- say the water in the Pacific Ocean. Now take any portion of that water -- say a handful of it that a person scoops up near Honolulu, one of its <a href="http://sw.opencyc.org/concept/Mx4rvVkGOJwpEbGdrcN5Y29ycA" class="cyc_term">physicalPortions</a> (a spec-pred of <a href="http://sw.opencyc.org/concept/Mx4rvVj7bpwpEbGdrcN5Y29ycA" class="cyc_term">parts</a>). That handful is itself an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a>. Hence <a href="http://sw.opencyc.org/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a> is a <a href="http://sw.opencyc.org/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a>, in virtue of the fact that all <a href="http://sw.opencyc.org/concept/Mx4rvVkGOJwpEbGdrcN5Y29ycA" class="cyc_term">physicalPortions</a> of all instances <a href="http://sw.opencyc.org/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a> are themselves instances of <a href="http://sw.opencyc.org/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a>. Other examples are: <a href="http://sw.opencyc.org/concept/Mx4rvf9sZJwpEbGdrcN5Y29ycA" class="cyc_term">AspatialInformationStore</a>, which is stuff-like with respect <a href="http://sw.opencyc.org/concept/Mx4rvVjCQJwpEbGdrcN5Y29ycA" class="cyc_term">containsInformation</a>; <a href="http://sw.opencyc.org/concept/Mx4rvWEA25wpEbGdrcN5Y29ycA" class="cyc_term">CharacterString</a>, which is stuff-like with respect to <a href="http://sw.opencyc.org/concept/Mx4rwLSD2ZwpEbGdrcN5Y29ycA" class="cyc_term">subCharacterStrings</a>; and <a href="http://sw.opencyc.org/concept/Mx4rvtUAU5wpEbGdrcN5Y29ycA" class="cyc_term">List</a>, which is stuff-like with respect to <a href="http://sw.opencyc.org/concept/Mx4rwQxEhZwpEbGdrcN5Y29ycA" class="cyc_term">subLists</a>. These examples are somewhat exceptional -- most <a href="http://sw.opencyc.org/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a>s are like the examples of <a href="http://sw.opencyc.org/concept/Mx4rvVi3c5wpEbGdrcN5Y29ycA" class="cyc_term">Breathing</a> and <a href="http://sw.opencyc.org/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a>. See <a href="http://sw.opencyc.org/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>, for the contrasting (but not disjoint) notion of being object-like.

Specializations of <a href="http://sw.opencyc.org/concept/Mx4rvf9sZJwpEbGdrcN5Y29ycA" class="cyc_term">AspatialInformationStore</a> include <a href="http://sw.opencyc.org/concept/Mx4rwClAZJwpEbGdrcN5Y29ycA" class="cyc_term">ConceptualWork</a>, <a href="http://sw.opencyc.org/concept/Mx4rvViA1ZwpEbGdrcN5Y29ycA" class="cyc_term">Microtheory</a>, <a href="http://sw.opencyc.org/concept/Mx4rwQGTzJwpEbGdrcN5Y29ycA" class="cyc_term">AbstractInformationStructure</a>, and <a href="http://sw.opencyc.org/concept/Mx4rvVi3N5wpEbGdrcN5Y29ycA" class="cyc_term">FieldOfStudy</a>. Although no instance of <a href="http://sw.opencyc.org/concept/Mx4rvf9sZJwpEbGdrcN5Y29ycA" class="cyc_term">AspatialInformationStore</a> has a spatial location, some instances can have multiple spatio-temporal "embodiments". For example, an instance of <a href="http://sw.opencyc.org/concept/Mx4rvViAqJwpEbGdrcN5Y29ycA" class="cyc_term">PropositionalInformationThing</a> may be the content of several concrete documents, such as several instances of <a href="http://sw.opencyc.org/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> (see <a href="http://sw.opencyc.org/concept/Mx4rvtEvQZwpEbGdrcN5Y29ycA" class="cyc_term">containsInfoPropositional_IBT</a>); and several distinct events, such as spoken utterances, may have a certain unique <a href="http://sw.opencyc.org/concept/Mx4rvViA7JwpEbGdrcN5Y29ycA" class="cyc_term">Proposition</a> as their content (see <a href="http://sw.opencyc.org/concept/Mx4rvVjCQJwpEbGdrcN5Y29ycA" class="cyc_term">containsInformation</a>). wikipediaArticleName (<a href="http://sw.opencyc.org/concept/Mx4rTv-jk9SPTXa991kk5mAvHg" class="cyc_term">wikipediaArticleName</a> THING NAME) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article with the title NAME Wikipedia Article Name
