One peculiarity I've found n my dreams is the presence of ever-consistent places which don't exist in the waking world. Yet, in the oniric world, they have their own existence, their geography remains constant throughout, and when finding myself in one of those places, I recall previous dreams and experiences there as if they were as real as the rest of my memories. What's more, they are all quite mundane, they're simply places to live which I could even place on a map in the waking world with more or less precision. Below are mentions of these places, as posted on my tumblr at the time, and maps I drew of said places.

My first mention of such dreams.

"So, there are places in my dreams which I've visited numerous times. Last time I dreamt of one of those, it was a psychiatrist's waiting room, a place I know I had dreamt of before and whose familiarity felt comforting. First time I went there was when I started my transition. Today I dreamt of two of those places, as they are both situated very close to each other, I the city I grew up in. One of them is in a shopping street, a little covered passageway with a thrift shop and an adult shop, and the other is a way home by the riverside/seaside. Not sure what those places mean, or why, after visiting them a few times, they feel extremely real and lost all their dream-like qualities. Honestly, I don't even know how to feel about going back to those places. It's just kind of weird"

Here is the mention of the countryside house and here is the mention of the English plaza.

"Visited another reoccurring place in my dreams tonight. Well, it was more of a nightmare really.
The place in itself is a house, on 3 or 4 floors depending on how you count. The ground floor is a classic house it the french countryside, with a garden and all. It is not very big, and mainly elongated. First floor is accessed through an extremely tight, fully enclosed staircase. It's essentially like an attic for people to sleep in, dirty, poorly lit with mattresses spread along the floor and visible wooden skeleton of the house. second floor is a library, accessed through another staircase than the one that brings you to the first floor. It is filled with CDs and vinyls and rare music records. The back wall of the floor is a shelf filled with books, and a ladder leads to the ultimate floor, a mezzanine which is part of the library, this time just filled with books.
As far as I remember, only nightmares ever took place in that house. Not sure what this place means, but I kinda don't like it tbh."

"Okay, so, another day, another thing to add to my general dream geography.
For those who have no idea what I'm about, I have this thing where some of my dreams takes place in these recurring, super consistent places. It is very much a part of why I have so much troubles distinguishing dreams from waking life sometimes, to the point where, at times, I have to actively convince myself that I'm back in real life when I wake up and I'm not just going insane. And these places are so coherent that I could, for a lot of them, actually tell you where they are and approximately how to get there *in real life*. And because these places are recurring, I have been to all of them several times and remember it clearly as actual memories.
This time it was a place in England. More specifically the place I arrive whenever I go to England in dreams. Now, the specific location is a huge plaza, going into plenty of small side streets. To the south is a connected, smaller plaza (with a BDSM dungeon which was actually relevant this time bc someone I was with, a middle aged woman who isn't actually anyone I know irl, actually used to frequent the place and was familiar with the people working there.) and to the north is a river coursing through the city, across which is the commercial district. I've only been there once so I couldn't give you that much detail tbf.
As for how to get there, this time was pretty standard. I took a ferry/train (actually a weird mix of both). But one of the previous time I went there was actually from public transport, after the subway in my town got renovated and now continued into a skyrail going across the English channel straight into England for more conveniant travelling. Which, funny enough, I actually remembered as a dream within that dream I had today."
