I used to have those kind of dreams quite a lot, I’d think that I’d woken up only to later realise my mistake when I finally woke up properly, still happens on occasion even now but now mostly its just dreaming that I’m awake. Gets very confusing at times.
Can’t say I’ve woken up with injuries much though, mostly my bruises are due to martial arts, and I can’t remember any of friends cheating on partners either I’m afraid.
