Strange thing happening

Last night (12 sep to 13 sep) I woke up i thing in the middle of the night, I said to my grandma to measure my temperature. The temperature was 37,3°C I was shaking because it was so cold. The temperature went down. We laid in bed, she fell asleep i didn't. And ten mins later I started "hallucinating". I was seeing white things fly past me even with my hand over my eyes. I tried to fall asleep on my right, left even on my back nothing worked. Then I got comfortable on my back. 5-10 mins later I was looking at the ceiling. Then I was seeing white, I said "La li laha illallah"(idk how to spell it) then i couldn't move and had that feeling when you strech after you wake up, tried moving my fingers, but only the pointer fingers moved, then i got out of it, scared, high heart beat, and breathing fast. Does anyone know what was that and what should I do? I am sick for now 4 days with temperature 38°C+
