question 18 (4 points)
according to freud, the latent content of dreams refers to
its accompanying brain - wave pattern
the previous days events that prompted the dreams
the sensory stimuli in the sleeping environment that are incorporated into the
dream
its underlying but censored meaning
question 19 (4 points)
the best indication that dreaming serves a necessary biological function is provided
by the fact that
most dreams are psychologically meaningless
the disruption of rem - sleep leads to narcolepsy
most mammals experience rem rebound
sexual tension is naturally discharged during rem sleep

Explanation:

Freud's theory of dreams distinguishes between manifest (apparent) and latent (hidden, censored) content. The latent content is the underlying, often unconscious meaning of the dream.

For the second question, REM rebound (when deprived of REM sleep, an organism later spends more time in REM sleep) suggests a biological need for REM (where most dreaming occurs), indicating dreaming (as part of REM) has a necessary biological function.

Answer:

Question 18: Its underlying but censored meaning
Question 19: Most mammals experience REM rebound
