3 nights of horror

My circadian rhythm is not on its best fit these days. For the third night, I have elucid dreams that are quite disturbing.

2 nights ago I dreamed of loosing breath (waking up having stiff neck)
a night ago, on my dream, someone I know got killed/died and there are spirit hunters mocking (that dream is so freaky I'm crying when I woke up)
just now, I got disturbed that there was an implant in my body that needs to be removed or I'll get electrocuted (waking with a body that has that feeling)

Am I thinking too much that my mind is still working on my sleep? Or is it my brain is too dead that it is looking for a way for it to function?

I can't sleep now...
