I only hallucinate when I blink

Decade old illness so the thought of complication comes to mind which is probably why all this sounds odd. I’ll cut to the chase, and explain more if needed, but that it seems like I am having split second hallucinations that I can never physically see anything but my body and mind seems to react to it like I did just not as harshly. The speed of these events are as short as an eye blink, can happen one after another, but don’t reach an actual continuum (the period between these back to back “hallucinations” are actually the worst). This typically happens when I open a door, turn a corner, or am in silence. May actually be an occurrence of my eyes being closed but I’m not gonna stop blinking because…well everyone needs to blink ^_~.
Is there a type of hallucination where none of the primary 5 senses are triggered (feeling so strong that my body is deceived in thinking I’m hallucinating). Can a visual hallucination manifest and go away in well under a second? Why cant I prove my senses are incorrect after a literal thousand times of being proved wrong?

It is said that we program ourselves when we our young letting our brains know what is what.
In other words an orange might smell different to you than it does me.

If I raised you when you were a child, let you sniff dog poo and insisted enough that oranges smell the same; every time you were to sniff an orange it would smell like dog poo to you.

When shifting vision quickly you’re catching a blur of shadows in your eyes that confuses your brain but your brain must associate it with some sort of pattern you’ve seen before.

Like looking into my neighbors back porch a few months back and seeing a large china doll’s face - careful inspection revealed coats and an opened umbrella on a rack.

You’re probably just doing this more than most people do - So keep checking with your doc.

Also I’ve come up with some really original cartoon ideas each morning on my back porch having a smoke and half paying attention to the patterns our rocks in our garden make.

Thanks good explanation. the “hallucination” (it’s an illusion by your description which is good news and why they aren’t so severe). happens 3 inches in front of my face or all around my head (actually actually all i actually see is the teeth as if im inside as they close down).
