After my second closing shift, I started hallucinating customers.

Hey guys, just started working at CFA about a month ago, I worked a closing shift last monday and after I got home I kept hallucinating customers coming up to me and asking for the most complex orders and I was panicking as I couldn’t find out how to help them with it. I legit had to keep telling myself that I’m safe at home and I’m not at work anymore. I know this might be kinda concerning but it’s pretty funny to me lol. I’ve never hallucinated like that before so it was pretty freaky but yeah. Does this happen to anyone else?
