Hi, I've Been Having A Hard Time Sleeping Lately. Not

Hi, i've been having a hard time sleeping lately. Not falling asleep, but rather staying asleep. I can wake up around 3am and then be awake. I've been having vivid dreams EVERY time i fall asleep too. This is fairly new (couple months). I also have been experiencing small, non painful muscle spasms. i can have them at night - or during the day. And - all over. Feet, hands, ribs, ear drum?!. It's odd. Along with this is what feels like a heart palpatation every once in a while. Not all day,but almost like anxiety - or a spasm? i'm healthy, exercise a lot, eat right. I'm not fatigued.
