Thread: Being unconscious, then waking up and convulsing..in a dream

I saw a dream, it was in the middle of other dreams that I remember faintly. I remember not seeing anything at all, and then waking up from being unconscious in my dream and having convulsions. When I woke up from being unconscious in my dream, I realized or had a sense, that the whole time I did not see anything, was me being dead / unconscious. So, you could say, I dreamt being unconscious and it was NOT from 3rd person's view, it was from 1st person's view, because I only remember waking up and THEN realized why I didn't see any dreams (I guess my mind realizes when it sees a dream), and then having convulsions.

It was in front of a whole class in my school. The class and the teacher I didn't recognize, I didn't see their faces, but I felt like they some were people familiar and some weren't.

Be aware that I really did once fall unconscious when I slipped and hit the back of my head and got knocked out, when wrestling with my friend on ice when I about 13, about 3 years ago. I remember my friends telling me that I was shaking terribly and having convulsions during the time I was knocked out. It was a minor concussion, it turns out.

What could this dream mean?
Thanks for any help.
