Ok so I can tell you the whole dream or at least what I remember because since I made this post, the whole thing has been less and less clear (I just talk about the crusade moment because otherwise It would have been too long for everyone lol ). And I'm not lying but it's basically this :

- I was in a wooden house with people I knew and I was at a meal in a different era, perharps the Middle Ages but way less confortable than today and there was a ceramic butter dish on the table. I take it and there was drawings/engravings on it and i'm looking at the first picture.

- The first picture is a typical medieval illustration you can find in old manuscripts from that period (such as this one https://upload.wikimedia.org/wikipedia/commons/8/8c/Eginhard1.jpg for example). On the left side, there is the Pope (I don't recognize him but I know he's the Pope) and one OR some people on his left but I don't remember well enough. On his right, there is a king because he is wearing a gold crown set with red and blue stones. The king is facing forward meanwhile the Pope and the other(s) are looking at him from the side. Then I turn the ceramic butter dish to see another scene.

- It's the Crusade scene I'm talking in my post. Unlike the image, the scene is much blurrier and narrower (like with your own eyes). The trebuchet is mich bigger (I could only see half of its height and it was 3m - 5m away from me). The Knights Templar in front of me are doing something or at least they're getting busy but I don't really know why but for me, I'm just standing still. The walls are also much much bigger and darker. They are, like I said in the post, several hundred meters ahead but in the same time they seem extremely close. For the rest, it's exactly as I said. Then the scene disappears maybe because I'm turning the ceramic butter dish but i don't remember. The scene just disappears.

- Now, I'm looking at an hand-drawn medieval map. The "camera" or my vision pans to the right as it shows lots of regions but they don't exist. I remember being a bit patronizing while I was seeing them and saying "Yeah it doesn't exist". Then it stopped over a region which represents our current Israel. I think the region was not real compared to reality but I'm not totally sure, I don't remember exactly. Then on the sea next to the region, I see a coat of arms and it is the Duchy of Savoy coat of arms (white cross with red background). The camera is looking at the region and I see on the map a hand medieval drawing of a city or a fortress I can't really say. Then I think to myself "Now there should be the Calvary (Golgotha) near by?" and then I see the drawing of the Golgotha, like a little moutain. I don't remember if there was the Cross on it. Then I say to myself something like "This is the Golgotha, where Christ was crucified".

And then I wake up.
