I've felt out of touch with reality the last few days. My vision would keep shifting to the right as if I...
I would say dissociation is really just "tuning out" experiences which by nature are mental health related . For me, dissociation can even extend to psychotic-like experiences, where i think i see some things, but they tend to be just ordinary objects in my environment - because i was lost in my head. Sometimes, it could be i was tuning into visual imagery, and intensely focused on that, that i was blankly staring into a space in front of me for a good minute or couple of minutes. this is frustrating.
Otherwise, i think what you are experiencing is more physical. Like, i was having dizziness and balance problems recently as well, and i rushed myself to the doctor. the doctor checked my ears, and gave me migraine medication (after he figured what i described was migraines). Really, it could also be a build up of wax in the inner ear, this tends to cause dizziness and disorientation as well. (use ear drops with cotton)
Likewise, eating habits and dehydration patterns can also cause dizziness (make sure to eat at the right times, and drink a glass of water after eating, or at least, more than what you are drinking now). Dehydration can cause dizziness.
I'm guessing you're not sick? (viral flu or fever or something?) If you are, then that is definitely causing all this, it is not uncommon to get vision problems as you described, when you are sick.
After all this, and seeing a doctor, if the problem persists, then you can worry whether it's temporal lobe epilepsy or a migraine disorder or whatnot. (assuming you're an intense ptsd-hypochondriac-worrier like me :p)
If you are feeling dizziness, what you are going through is purely medical and physiological. eventually, you will find treatment, just like i did. and it gets better at a future time.
