[Vanishing Point]

Yes. Walking into rooms forgetting what I was doing, putting plates in the trash etc. I have actually walked straight into a wall and a palm tree while being zoned out, ie engrossed with what was going on my head.
That said I can recall things if I have to: for example I was told I had said something that didn't sound at all like something I'd say. It took me three days of being bothered before I could recall the context and slowly snippets of the conversation began trickling back and could remember the exchange.
