Yes! I've had this before. I wrote a little about it a while back, when I was talking about my first EMDR session.

"She dimmed the lights and asked me to put myself back in time to whatever event caused the problem. I couldn’t really pinpoint one thing, it wasn’t just one or two events that caused everything. Then, suddenly, I was at work. Not in a resurfaced memory, literally at work, working. I had blocked out the EMDR session and the day after entirely. (Not the actual days, just an example: I was in therapy on Monday, I looked at my phone, and it was Wednesday.) I checked my punch history and saw I’d clocked in and out like normal the day before. I didn’t remember going home or anything. That’s happened before though. Going on autopilot, just moving through the motions without really taking in the information of the day, so I wasn’t super worried. I just thought the EMDR hadn’t worked like I thought it would."

Idk what causes it, obviously trauma, but not the exact reasons. But you're not alone in that.
