Not entirely sure if we were abducted, but my wife (who was a non believer) and I both have missing time. We were having sex on our bed when we suddenly both came to, and were in totally different places in the room. Not sure how much time had past, but she looked at me and said “what the fuck just happened?” I said I wasn’t sure. Neither of us were scared, and we were both incredibly tired. We decided we would just go to bed and talk about it in the morning.
I looked up instances of missing time and a lot of them said the same thing. When they came to they were just very tired, knew something was totally weird, but just wanted to go to sleep.
Edit: We had a carbon monoxide detector. Fully functional. It was an apt. not a house so it was routinely checked and up to code at all times.
