a very beautiful purple dream.

So, I'm not sure if I had ever seen dreams like that, and yesterday it was a whole film, a ghost film, a whole ghost film very visually beautiful and aesthetically pleasant.
Last night I got back home and was feeling incredibly out of space and couldn't draw or work on my dissertation so I looked at some picture books, then watched some short films and then switched off on my bed.
And when I woke up in the middle of the night, I could perfectly remember the dream I'd just seen, and I can still remember it now (I was terribly afraid I wouldn't).
So, there was a castle. I did not see it from the outside but been to many rooms inside and experienced them in detail.
It had that room I used to see a lot in my dreams in May and June last year, a room somewhere in the cellar areas of a dark gloomy building, with silver dust and spiderweb patterns all over the place, dripping water and somebody coming up the stairs just in front of me up in the darkness of the stairs, but I could never see them properly. I can remember it properly even this very evening and although I haven't seen this room for a while, I saw it last night but this time with some more to it, with the whole castle.
(to be honest, when I woke up, I was incredibly overwhelmed by everything I had seen, but I don't think I can remember all the details now)
The rooms and halls and corridors in the castle had a touch of time to them, the interior was very intricate and highly different and weird, it had mirrors, a lot of stairs, beautiful wallpaper, the colour palette mostly silver, blue, dark navy, black, some red, and greyish blue. The creatures I was around but they couldn't see me were some kind of ghosts, I could see though them, but feel them and hear them talking, the weren't walking on the ground, more like floating in a way, and the most impressive thing was they would have some kind of purple mist, a cloud of purple dust around them, this aura of them was more visible and rememberable than their own matter itself. A man had dark curly hair, shoulder length and the lady, can't remember her face properly, the hair had a tint of dark gold and she was wearing glowing early victorian with some Elizabethan jewelry details clothes and had tattoos on her arms.
I can't recall what were their conversations or plans like, the visual part was the strongest.
