These phenomena express “conceptions” of things like the world according to Calvin Hall’s continuity theory. In the AIM (“A-I-M”) model, these phenomena are caused by interactions between aminergic and cholinergic neurons that generate PGO waves; that model of these phenomena is based on Hobson and McCarley’s activation-synthesis model. Echidnas’ large frontal cortex inspired Crick and Mitchison to theorize that these phenomena cause “reverse learning.” Antti Revonsuo theorized that these phenomena simulate probable threats. These phenomena act as “wish fulfillment” (-5[1])according to an 1899 (10[2])book that described a precursor to the Oedipus complex. For 10 points, Sigmund (10[1])Freud wrote about the “interpretation” of what phenomena that occur during REM sleep? (10[1])■END■
