dream vs reality = idk

I woke up sweating in my sleep like crazy. this is the 2nd time in a while. this weekend I had a party filled weekend. so I slept super long yesterday night and yesterday all day until my boyfriend brought home dinner after work. as he was getting ready for work, I was still sleeping but I thought I heard him whispering to me knowing he left. I kept trying to open my eyes but they wouldn't open. I couod feel myself saying stop stop. it was weird and creepy. so I guess I was still dreaming cuz I thought I got up and saw he came back or didnt leave yet... but he was already gone. strange... then I had the full on dream that I got up to drive home but I obviously didn't. but in dream state I did drive home, got lost and transported to another planet??? like I left earth and was told I had to leave everyone and everything behind, including my mind. I was going to have a different conscience and a different life on a different planet. was so real and so... scary. I was relieved when I woke up and realized it wasn't real. 

after sleeping all night Saturday, all day Sunday and just now all night again I had more vivid dreams that I couldn't figure if they were real or dream. I thought I was laying sideways at the end of the bed while my boyfriend was asleep. I was watching tv and eating Graham crackers. which sounds realistic for me but guess that didn't happen. woke up and had to take my shirt off and put a towel down cause the bed was wet from sweating so bad. when I go through dreams like these I get super worried I'm going to die or something bad will happen and I can't see my bf or family. hate that. and if it isnt really happening soon I don't want it to happen ever :(
