Can't sleep at night after falling asleep waking 10 minutes after happens several times per night why?

Sleep disorders are relatively common, and these include garden variety insomnia, depression, panic attacks, restless leg syndrome, sleep apnea, periodic limb movements in sleep, REM sleep disorder, and narcolepsy with hypnogogic hallucinations. Any of these conditions could prompt irregular sleep. See a sleep specialist and do an overnight monitored study.
