Dream About Hotel College University Room Too Small

I had a dream last night that I'd been away somewhere. I think, I think I was at a hotel and I think it was like a dream I've had before where the hotel was also a college or a university and I was having to walk through places to try and find a room and then the room was really small, almost too small, and then I was getting the train back and I was really looking forward to going home because I was so tired and I sat on the train and I was thinking I was going to have to get the train miles away from home and it started going down the road where I used to live when I was a child and I was like brilliant I can get off early. So I rung the bell, got off the train and it stopped just after the bridge and I got off the train, although it was more like a bus because it was on the road, and I had to walk over the bridge to get back home and I remember I was dragging my feet because I was so tired and I was barely making it over this bridge and I went across the road at the top of the bridge and there was loads of emergency vehicles driving down and I had to really time it right to get over the road because I couldn't go very fast but I only had a small gap so I got over the road, walked down the old road where I used to live and walked down this little thin alleyway that was there and I walked in the back garden and my mum had been in the garage and she came out and she goes, oh we weren't expecting you and I said oh I've managed to get the train closer to home. Anyway, I dragged myself inside, put my stuff down, dragged myself upstairs, I was so tired and I went to see Abby in her room and Abby wasn't in her room, there was a boy in the bed, paddling this blonde girl and I recognised the boy as Abby's boyfriend and I was like I don't know who she is. So I finally said hello, he said hello, I went round into the next room and Abby was in there and I said oh Abby, you're not in your bed, she said oh no my boyfriend's in there and I said okay who's that with him and he said oh just a friend and I said well who's cuddling her and she said yeah I know and I said well that's not right is it. So I was like I'm not having this. So I then went back into the room where the boy was cuddling the girl and I threw them both out and then I said to her I was like right I'm going to sort this one out once and for all. So I got her phone and I started recording voice notes to him saying how it wasn't appropriate that he was doing that and even if Abby was alright with it, it wasn't alright and he shouldn't be doing it and I left about fifty voice notes and she was just like oh right okay and I was like I can't believe this, I've come back and I'm so tired and I'm having to sort this out.
