shakiness and feeling heartbeat

Sounds like an anxiety or panic attack to me. I get really anxious a lot too. Maybe you should see a Dr. I havent seen a Dr. About this, but I should. I'm just too sacred to go. If you find any remedies, let me know :)

Actually that reminds me of the time my doctor put me on some sort of medication. (i cant remember what for anymore) I remember I had a horrible reaction to the medication. I couldnt relax, my body was always so tense, I always had to be pacing, and it seemed to make me have anxiety problems. So, my question is, are you on any medications? How long have you been on them?

Hope this helps

Coming from a first-aider... You could be experiencing anxiety... But when ur sleeping.. It sounds weird.. And hearing ur heartbeat and all that u've mentioned also sounds like low blood pressure to me... I generally have low blood pressure... Hypotension... I can hear my heartbeat sometimes.. And feel like I can't sit still and feel weak... But yea.. It could be bp problems. Hope this helps =)
