Can anyone explain this?

I had such an odd thing happen last night and wondered if anyone had any insights. I woke up needing a wee (happens every night) so, as usual I lay there for a while wondering if I can risk going back to sleep instead of going to the toilet. I remember while I was laying there I was thinking about what time I should go to the garden centre in the morning, and what I wanted to look at, so I was definitely awake and lying there for a while. Anyway, when I finally went to the bathroom, the door was shut so I assumed my daughter was in there (I could hear her moving about), I knocked and as soon as I knocked it was sort of like I had a nano second consciousness slip...sort of like a second of just...blank and slightly jarring and literally for less than a second, then I realised the bathroom door was open a bit, not shut, I pushed it open and no one was in there. I was SO confused! It was SUCH a bizarre feeling! I sat on the bath pondering it and then went back to bed..to add to the weirdness, last night at 7:14 I was sent a photo of my cat sleeping in my mixing bowl. I replied and he messaged back saying I'd replied before he had even sent the message. I'm going to assume I haven't suddenly started time travelling 🤣 but what in the world was that!?

In addition (if it's useful), I also had a bizarre moment a couple of years ago in Christchurch Mansion (a huge mansion which is a museum), it was late in the day, dark and raining and it was just me and a couple of other visitors there, as well as my partner. My partner was in another room looking at things and I moved down a short corridor into another room, the room was completely empty, and the house had been silent before I entered. As soon as I walked into the room I heard plates and cutlery clinking, laughter and conversation, just like I'd walked into a party. I remember thinking at the time, "...this is NOT normal!", a few seconds later my partner came into the room, the noises stopped and she hadn't heard a thing. (I'd also like to add that my mum told me something similar once too that had happened to her. She was in her 20s on an archeological dig and woke up in her tent hearing the sounds of war outside. Obviously there was no war, she was in a field, however the field had been the site of a battelground many years ago (hence the dig).

Thank you in advance for any insight!
