Forbes debunks some myths about sleep and sleep disorders.

If you can’t recall your dreams, you’re not sleeping deeply. Not true. It’s normal not to remember your dreams, but most likely you are still having dream sleep otherwise known as REM (“rapid eye movement”) sleep every night. In fact, most people remember their dreams only because they may be waking up frequently in the middle of the night (from disorders such as sleep apnea) or because they were in the last stage of sleep when the alarm went off.
