I think that the idea of Dreams within Virtual Humans is fascinating, and closely related to Memory and Internal Narrative. There are two/three particular aspects I’m interested in:
How dreams are generated when the VH “sorts” its memories from the day whilst asleep
How dreams can be used to rehearse awake period actions (which allies with day-dreams)
How dreams could actually take place in a virtual world, so the VH literally loves them out and, like us, cannot tell that they are not real whilst they are happening.
