I have had the exact same problem since a week after my injury almost a year and a 1/2 ago. I agree it is like a
Bad drug trip. My neuro ophthalmologist Put me on topamax treating it like I a migraine aura but it didn't work. I've gotten used to it somewhat I can take it over the dizziness that I'm fighting any day. I notice when I'm tired it can get worse and especially noticed in low light settings. Going through neck therapy presently as all the specialists think there is a neck component to this problem.
