Dream facts
- Most dreams last anywhere from five to 20 minutes.
- People don't only dream in black and white, as was once believed.
- Even though they may not remember them, everyone dreams several times a night. In fact, during a typical lifetime, we spend about six years dreaming.
- People who have been blind from birth have dreams that are formed from their other senses (e.g., touch, smell, sound).
- When people are snoring, they're not dreaming.
- Elephants (and some other animals) sleep standing up during non-REM sleep, but lie down for REM sleep.
