I have the same thing. It's called a Panic Attack and they happen out of nowhere in your sleep or just being in a uncomfortable position. I would be just walking and My eyes are open but everything goes black, so weak, sweating, dizziness I cant breathe and i thought i was having a heart attack. Its terrible but i take medication for anxiety for about 5 years now, i started having this when i was 16 to and i am 19 now. The medication really helps.
This happened to me today at school I wasn't cold and I didn't have goosebumps but I had nobody to help me and there was nobody around so I felt for a wall and then closed my eyes for like two minutes and when I opened them again everything started to come back together and I went back to my lesson feeling perfectly normal
Hi, I'm 14 female and I was just getting out of the bath when it all happen. I could not hear it was being reduced and my sight it was Turing black from the outside and I was having a hard time breathing I was breathing really hard like I just ran a marathon and I felt really dizzy. And I could hear but I couldn't at the same time I was telling myself something but I could not hear it it was all fuzzy and my eye sight was going dark but after five minutes it cleared up. Any idea what happen to me?
