Weird symptoms when waking up? Please help!?

For the past week or so, ive been waking up sweating, out of breath, weak, shaking, sore, and pale. I don't know what it is! I get 9 to 10 hours of sleep every night. It started off with just waking up with bruises all over my legs for no reason, then i got all of these symptoms, now i get horrible vivid nightmares, too. Also, when i wake up, i have a hard time remembering the day before. It just seems like it wasnt real. I take vitamins everyday too. Im not on any medications, i do not do drugs or drink. Also, (this Im not sure if this is related) I've been zoning out a lot. I feel like life isn't real and I'm not real. Ive been feeling very anxious and depressed, too. I do have an anxiety/social anxiety disorder, but lately its been bad. Please help!
