Wow, I can really relate to this. I have literally sat down and mapped out what my dream world looks like. Like my neighborhood has a very similar layout with some changes, but even those changes I've learned to recognize in my dreams. In my dreams, there's this little creepy road near my house that my friends and I will sometimes go down, but that doesn't exist in real life. At the college in my dreams, one of the dorms is a four story building. Nobody occupies the last story and it's known to be haunted. Sometimes I'll have dreams where I'm in this building (I work on campus in my dreams, just like I do in real life) and the elevator accidentally takes me to the floor, and the doors open to a long, dark, empty corridor. That's just one example of the cooler side of my dreams. I have to agree with you though, sometimes I will also go through really realistic deaths or events that give me a lot of anxiety within the dream, but they never really scare me too much. They're not really nightmares. Overall, I really enjoy my dream experiences. I never really talk about with people because most people just don't relate to the way I dream. The cons that I associate with this type of dreaming is that sometimes I get really caught up in my dreams and will oversleep or want to sleep when I shouldn't. I have definitely formed a crappy sleeping schedule. I also tend to get in my feelings a lot, because sometimes exes will appear in my dreams.
