As suggested by a few psychologists, people who say that they never dream are
- obviously bluffing.
- In fact waking themselves up during REM sleep.
- Not trying to listen to what their dreams are saying.
- Depriving themselves of a chance of attaining their unrealized desires.
- None of these
Solution : Not trying to listen to what their dreams are saying.
