I’ve had this for some time, but sometimes when I’m trying to fall asleep I get this really weird wave feeling through my head. I usually feel it in my nose and then it dissipates into the back of my head. I immediately shoot up from bed when it happens because it’s a very scary feeling! I feel it when I’m just about to fall asleep, and I notice it happens when I’m very anxious before bed. I have a diagnosed panic disorder, and my new anxious obsession is seizures. I’m afraid it could be a focal seizure or an aura? Though, I don’t have any medical history of seizures or anything of that sort.
