Really weird thing just happened

R
So I'm taking a nap and shortly after I wake up, I'm dripping from head to toe in sweat and feeling shaky. I took my temperature and no fever at all and it's not hot in here either. Turned the fan on which made me cold but was still sweating. Got really hungry all of a sudden and ate and craving something sweet now. 37+2 and this has never happened before. Other than the extreme sweating and a little shakiness I feel perfectly fine. I'm so confused! Any thoughts on this??
