What does it mean if your not having dreams?

Everybody dreams during sleep, but the great majority of dreams are forgotten. It is not unusual to feel as if one never dreams at all, but this only means that dreams are not remembered after awakening.

It is also possible that some factor could prevent a person from entering the REM (rapid eye movement) phase of deep sleeping that is required to dream. Certain medications can have different side effects with different individuals, and dream disturbances are known to occur. However, actual lack of dreaming for more than a few days could cause both physical and emotional harm.
