Is it normal for my dreams to take place in a multitude of demensions?

I have never heard of anything close to what I believe to often experience. My dreams all take place in one universe, in a way. But, there are multiple levels of being in them. At each level there are even many parallel timelines. When I'm awake I only know some of the framework, like what I am describing right now. When I fall asleep, depending on what reality I "wake up" in, I remember every detail that has happened in what feels like real time. Most commonly I'm in a 3rd dimension such as ours. There are two timelines / existences here. One is like a video game but actual life, generated and processed how we understand the real world to be. The other world at this level is pieces of my real life mixed into a completely realistic alternative life that is still mine. All the laws of science are the same here, but the politics of everyday life are different. But it's comforting. I even have fallen in love with a girl that vanishes from memory place I realize I'm really awake. I never know when I wake up that it's real life, because my dreams honestly feel much more real and detailed. I love it. But then I move over this 3rd demension into a 4th where it's almost like I'm experiencing my worlds without time. It has no order but is by no means chaotic. When I move up a level, I understand that dimension and all the ones beneath it. But once I go down, per say, I don't know of the higher levels, but at the same time I do. It's a lot like double think in 1984, but in good faith. I can't explain anything above 4 at all, really. Maybe the 5th level / dimension slightly, but only in the fact that it is the 4th without censorship. I only understand this when I'm asleep. I don't reach the higher level very often, as each increasing level becomes much more rare. The highest I believe I have "existed" in was the 8th, according to my reality based understanding of the realm. All I remember is swirls of light that doesn't have any colors that exist. I heard a powerful voice that had no sound to it, as contradictory as it sounds. I don't really know what else to say. My dream state, you can call it, is far more advanced and detailed than our earth. It's not frightening at all, which scares me. I should be worried but I love it. It is my home in a sense, it is my teacher. I exist.
