This is likely a migraine (believe it or not they have auras and can make you feel strange too!), if not they could be partial seizures that aren’t spreading (which is good). Do you feel “brain zaps”, like electricity/glitches in reality?

Only sure-fire way to know what that is, is to get an EEG. While having an eeg, they run many tests on you. It’s like a torture device lol.

They flash lights in your face at increasing and decreasing speeds, put head phones on you that have this loud as woodpecker sound get louder and louder, switching slowly from one headphone to the other, until that shit makes you dizzy.. you also have to hyperventilate for 5-10 minutes, which is the worst. My body shakes like a mother fucker uncontrollably (doesn’t feel seizure related), after forced intense hyperventilating (they tell you to go as hard as possible, it’s not like being out of breath from running, you breath in fast and hard, breath out fast and hard).

But yeah dude, an eeg would tell for sure even if you’re feeling partials. I suspect it’s migraines tho, and those are no fun either! I believe eegs can measure those too, not sure.

Edit: you should check my comment above about:

It’s not a psychoactive or scheduled drug so a doctor would have no problem prescribing it. It could improve your quality of life!
