I have the same dreams with small variations.
A bit of an unsettling story ahead here.
I recently just woke up from a dream that shocked me to my core. It wasn't so much a nightmare as it was an experience that I wish I didn't have.
In this dream, which I dubbed the "Family-go-round", you sit in place on a semi-circular ride as it goes around. It's sort of like an on-rails shooter, you don't choose where you're going, you simply go around and around, looking at different things that happen to you.
Each time you go around, people or things will interact with you. The setting seems to be a sort of family hangout, in sort of a back yard. The rail you are on is like a train that goes from one side of the yard to the other. Every time you leave, it fades to black. Every time you return, you see... well...
What you end up seeing is the same experiences over and over, but blended together like they were put in a paper shredder. A member of a the family looks at you and says something. You look over the fence and hear a snippet of audio, a voice line, over the neighbors doing something. You look over the fence again and their very strange looking dog is looking you dead in the eyes. This time around I saw a creature with multiple eyes. Not hostile, just there. Sometimes it's just your family relaxing, but something simply doesn't feel right.
Where it gets strange is that it's possible to start to take these slices of experience and piece them together. You start to realize, that voice clip doesn't belong here, it belongs here. You recognize that toy was in a different place, and said something else. Once you see the same "portions" over and over, they start to feel familiar, just jumbled.
Where I got truly unsettled is the fact that I have the ability to have the same dreams multiple times, and each time I do I'm able to pick up on subtle differences between the last time it happened. This can even include returning to the same place in my dreams, but having a different experience. Some of them almost 10 times now. I keep a log of these sorts of experiences, including how many times I've been to these places, and whether I'm alone or with others. I've also had recurring dreams that are simply the same dream again, but I'm able to notice that I've been through it before, so I pick up on things I never noticed before, as like this one. People only ever seem to talk about having the same dream repeatedly, not having different experiences in the same dreamscape.
Anyway, because of the uncanny nature of this dream, it's starting to turn more from a surreal experience into a nightmare. I have had this same dream maybe 3 or 4 times, each time slightly different, and I believe this is the second time that I became lucid (ish) and realized that the pieces can be put together. I don't want to put together these pieces, and I'm scared of what happens when I actually "solve" it. It feels like it's hiding a dark secret and I don't know why it feels so uncomfortable and hostile for what should be an otherwise happy situation.
Anyways, that's all I have. Sorry I can't be more detailed, it's hard to remember it all on account of the style of dream. I'm curious yet cautious to know what will happen the next time I have this dream, since it feels like it was no coincidence, and I'm a little terrified to learn the secrets that lie behind this dreadful yet slightly comforting scene.
