What causes bad dreams and palpitation of the heart?
human
Every night I go to sleep but wake up at exactly 4:22am and I feel as though my heart is racing as if I had a really bad dream however I have absolutely no recolection of what  was dreaming about. This has occured every night for the last month and it doesn't matter what time i fall asleep.

HiThanks for using healthcare magicI think, you have night terror and due to that you have sleepless night. In that case, you can try some benzodiazepine at low dose. That would help to get sound sleep. Better to take them on sos basis after psychiatrist consultation. That would help to keep the dose in limit to avoid dependence tendency. In case, you need further help, you can ask.Thanks
