Sometimes things look strange when I am dissociating, too. Like sort of "distorted glass" or things seem "off" like you said, Motown. I actually have ocular migraines too and this is nothing like those. (In my case an ocular migraine is brief, temporary blindness/starry spots in one eye).

Other ways I feel dissociation is that I can see that my body is here with my eyes but I don't feel connected to it... my body feels far away or like it's not mine. Other times I will feel like I've pulled back behind and slightly upwards from my body.

Also many times when I start to think about something that is emotionally upsetting, a switch flips in my brain and I will immediately forget what I was thinking about just a moment before and even forget what I was feeling, and it's replaced with a blank nothingness. I can't retrieve what I was thinking about even if I want to. Very annoying if I am deliberately trying to journal about something or work with a memory.

So, I would also say yes it's possible that what you are experiencing could be dissociation, but you could get checked out by a doc, too, to rule out any ocular or neurological things it could be.
