I woke up last night at about 1.30, feeling really confused and disorientated, and pouring with sweat. I think I was still half asleep and I could see words sort of hovering in the air in front of my eyes. I then had what felt like a seizure, where my arms and upper body went rigid and then started to shake. The whole thing only lasted for about two seconds and then I felt properly conscious but really exhausted. I didn't go back to sleep at that point because I was a bit scared, tbh, but once I started feeling more normal I did drift off and there was no further incident.
I'm not sure what I should do now - I have a headache this morning and feel a bit spaced out, but nothing I can really put my finger on. I've tried calling both 111 and my GP but both are so busy that I can't get through to speak to anyone.
I don't know what happened, I don't have epilepsy or diabetes and I'm not on any medication. As I was half asleep I can't be 100% sure it even happened and it wasn't just a waking dream. I don't think it was though. What would you do??
