The activation-synthesis hypothesis of dreaming states that

A) the purpose of dreaming is to express unconscious wishes, thoughts, and conflicts.
B) there is no purpose to dreaming, dreams occur because of random brainstem signals.
C) the purpose of dreaming is to resolve current concerns and problems.
D) dreaming is a by-product of a process of eliminating or strengthening neural connections.
