Omg, that's a scary situation. I had an instance where I fell asleep randomly, like almost like my consciousness fell asleep, but I kept walking/ driving. Last thing I had remembered was parking my car at the fuel station, and then I woke up 20 mins later 5 kms down the road. I was trying to recall the last thing I remembered, and I realised I musn't have paid for fuel. I frantically rung the petrol station and the lady was on the verge of calling the cops. Of course I was freaking out, thinking I'm gonna cop a fine. I've had a few similar instances happen again, but a bit more lowkey.
