camouflage-1297384_1280Tuesday Night Lecture – I was going to record the lecture but turns out I have no voice left with this cold.  Therefore, I will ask that you write down the following points on your ppt notes that are attached to the sleep lab!  Also, watch Crash Course on Altered States.

NOTES:

Why do we dream?

  1.  Freud’s Theory- (wish fulfillment) dreams are time for the id to express itself; they reflect our innermost desires that are too threatening to express directly.  Thus, dreams have manifest content (the literal narrative) and latent content (the underlying meaning)
  2.  Information processing – dreams facilitate memory by rehearsing important events; dreams are bizarre because we incorporate other memories into them.
  3.  Activation-Synthesis theory – the brain periodic “exercises” during the night by sending random electrical impulses; dreams are the brain’s interpretation of its own activity

Hypnosis

  1.  an interaction in which on person suggests to another that certain perceptions, feelings, etc will occur spontaneously.
