If people are deprived of REM sleep because they are awakened before they can enter it . . . then their personalities disintegrate and impairment of their mental functions soon follows.
When people are prevented from dreaming they will make up the loss by staying in REM sleep longer and presumably dreaming more often (about twice as much) until they catch-up.
Even though people "must" dream, it appears that they do so less and less as they get

does not mean that we dream less! Perhaps our physical reactions to our dreams decrease
