Answer 1

Answer:

Dreams as memory aides

One widely held theory about the purpose of dreams is that they help you store important memories and things you've learned , get rid of unimportant memories, and sort through complicated thoughts and feelings. Research shows that sleep helps store memories.When you read this sentence, the odds are that your brain is doing something quite strange and astonishing: you are not just looking at and scanning this text with your eyes, your brain also "speaks" the words of this sentence in a "silent voice" inside your head and you can "hear" this with a kind of an “inner ear”, however without any physical, external sound sources present. It is as if you speak and read the text out loud to yourself, but you do it all silently inside your own head.This phenomenon of our so called "inner voice" has been given many names and synonymes like "silent speech”, “inner speech”, “inner talk”, “silent talk”, "covert speech" (as opposite to overt speech when we speak out loud to others), "inner monologue”, “auditory verbal experience” or more despicable sometimes "auditory verbal hallucinations" (especially when discussed in the context of certain mental states like schizophrenia or paranoia).
