Vivid dreams?
 

One symptom I seem to be having pretty much every night is vivid + strange dreams, sometimes accompanied by night sweats if I'm too hot (this happened last night after I opened the window in my air-conditioned condo).

It makes sense to me that someone who has suffered a concussion might experience unusual dreams - after all, your brain has been thrown for a loop, and is busy trying to heal itself. But it would be nice if things started to settle down and this happened less often...

I got that for the first couple of weeks.

I would also wake up in the middle of the night hearing a loud "snap" in my head. It was like an electric snap.

It all settled down after about the 2nd or 3rd week. I am at 2 months now and sleep fine.

The only issue I have now is brain swelling...due to the slightest bit of activity. So annoying.

I had awful nightmares and vivid dreams in the beginning few months...which settled down..but I don't sleep well still 8 months later.

I noticed it more if I took tylenol pm or advil pm. so I stopped taking it.
