Sleeping disorder....HELP..!?!?!?

Okay so I haven't slept in about 10 days, I mean I sleep but I only get REM sleep meaning I sleep but not fully asleep and I dream the WHOLE NIGHT and wake up in the morning fine. But not refreshed. I usually sleep amazing during the night but these past days I just couldn't sleep and I have no idea of why. I am not even sure if i am stressed or not there is just so much going through my mind and I dream through the whole night about random things. i can even remember my dreams. During the day when i am up I feel like taking a super nap but I fight it and I think it is the cause of my sleep deprivation. I took a nap the other day for about 2-3 hours and I woke up feeling refreshed and amazed, I can possibly have temporary sleep amnesia but can you please give me some tips and tricks on how to cure this so I can go back to sleeping throughout the night and waking up refreshed!!! Please help. Thanks in advance. Ps. I am 21 years old and i don't take any meds (I'm a natural remedy freak) I don't have any diseases or infections from what i'm aware of so my health is pretty fine / good. I can say i have been going through a bit of stress lately though..
