Sexual abuse/assault?

Trigger Warning: possible sexual abuse

I feel like I can’t really post or ask this since I know people have been through worse. But I was laying down with my boyfriend and was dead asleep. But all of a sudden, I feel a tug at my pajamas pants & thought of my boyfriend & felt rubbing but I let it continue because I thought I was having some type of sex dream about him. I was like in and out of consciousness, I thought I was dreaming. So I don’t know what exactly happened during that night, how it started, if anything else happened. I just remember vaguely that and I swear I felt him physically move away from me. I don’t know how long after that happened that I had woken up to my own hand down my pants with no recollection of what had just happened. I just remember wondering why I had my hand down my pants, (I didn’t remember doing that at all but just thought I might have done it in my sleep) and after that, I pulled my hand out and looked over at my boyfriend to see him on the far end of the bed. And remember, I don’t remember what had happened so I’m laying there, still half asleep and wondering why he was laying so far from me and why he wasn’t cuddling with me. So I just turned to my side and fell back asleep. I woke up that morning, thinking “oh thank God that was just a dream”. But throughout that day, I kept wondering about it because I remember hearing.. it. Like those (sorry if tmi) but wet noises when stuff like that happens. I kept thinking maybe it was just lucid dreaming? But I kept remembering how I woke up, with my own hand down my pants and kept thinking maybe I was the one who did that? That maybe I started doing something to myself and I just thought it was a sex dream about my boyfriend and thought it was him doing it? Because the next night, I had fallen asleep next to him. I don’t remember how long I’d fallen asleep for but I woke up to him scratching me and moving his hand past my shorts but not enough to where he was touching me there. I immediately froze because he thought I was still asleep. That’s the first time he’s ever done that before because when he scratches me, he’s never gone past my shorts like that. So I thought about the night prior, that it could have happened because of what he did the second night. But I still don’t know how the night prior to that started off, what happened. Like why I had my hand down my pants, idk. I just have a lot of questions.
