It completely feels like I'm blind even though technically I can see. I loose sense of what I'm looking at is and where it is even though it's right there. 

It also happens with words I Know. I completely blank on the meaning and even the concept of the word as if hearing it for the first time but not recognizing it as a word, rather it seems a foreign substance. Like touching something blindly in the dark that you can't recognize what even the substances is.

I don't know if I'm making this up or not.
