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...
