Screaming or howling

<PERSON> I was going into Dallas and I's bathroom. It was very dark. I had to get up out of bed to poop. I started to sit on the toilet, when Dallas came into the doorway and started coming towards the toilet. "What are you doing? I have to poop!" I said. He kept coming. I got up. I assumed he had to poop too. "Are you really going to make me use the other bathroom?" I said. He did not say anything. I took that as a yes. I started to head towards the doorway to our bedroom to go to the guest bathroom. Dallas started to shut the door to our bathroom. I then started to hear noises coming from the living room area, and started to panic a little. Someone was in our apartment. Before Dallas could shut the door all the way, I caught it with my hand. I said something like "Dallas, someone is in our apartment!" I started to panic, and all my vision went black. I tried to scream for Dallas, but nothing came out. I then realized that I had been dreaming, and decided to calmly wait for myself to awaken instead of panicking. I then woke up on Dallas's chest. Phew, just a dream. I was so glad. I then started to hear noises again. I was really confused. Was I not awake? I started trying to wake Dallas up, but he was dead asleep. I pinched him, I tried to yell his name but again, it would not come out. Really? Is this really a dream again?I thought to myself. Vision went black again, and then I woke up for real. Another 10 minute nightmare. I was not asleep long at all. ~ I was at a bowling alley bowling with Dallas, but it was more like ski-ball; we were throwing smaller balls at the pins down the lane instead of an actual bowling ball. There was almost no one there; we were the only ones playing. Dallas then said something about how the bowling alley was closing for good soon; it was going out of business. I looked around and I could see why. It was so dead in there. I then went to throw my ski ball, but it slipped out of my hand and I accidentally threw it behind me. I then saw a very small child, a male toddler, carrying what looked like a six pack of beer up to the lanes, but it was actually a six pack of ski balls. ~ I had these two cakes made for me. I was at work I believe. Both were big and delicious looking with cream cheese icing on them (freakin yum). One had off-white cream cheese icing with red decorations. I had to do something with them to keep them safe or something, I cannot quite recall. Then, I saw the outside of my apartment. Someone was coming up the stairs. It was daytime outside. Then, something happened; a roll in a bag of rolls died? And it seemed so inconsequential, but I could not proceed with anything at all now. It was like playing a Sierra adventure game, where you do not do something in the beginning of the game and you get to the end and you have to start all over. I had to "start over" from a point before that to see if there was anything I missed, anything I could do to prevent the death of the roll. ~ Yay insomnia! Again! Woohoo. Also these 10-minute nightmares are very puzzling to me. It has happened to me quite often in the past few months. I guess what I do not get it how am I dreaming without being in REM? I thought REM sleep came later in the sleep cycle? Like, I will literally be asleep for 10-15 minutes for these nightmares. There was one that I was asleep for about an hour. Anyone have any thoughts?
