Unfortunately this happens to me a lot, I can suddenly not know where I am or what I'm doing, I can go in to what should be a very familiar place yet not recognize it, it looks kind of familiar yet not at the same time.

I can do something, for eg get something out of a cupboard and not realize I just did it.

I am seeing a neurologist and he suspects some kind of seizure or non epileptic seizure, not saying this is what's going on but it is disturbing when it happens.

How long do these spells last for?

I just wait for the spells to pass, they don't last long but they really disturbed me at first.

Are you seeing a neuro?
