Islam what could this vision means ( serious answers only)?

Okay i was in my english cl siting at the front. We had a sub so everyone wad being and not listening. I was sat on my own and to be honest wasnt doing much work. I was bored, sat there chewing my biro till near the end of the lesson. I decided for sum reason to look through my birow and i suddenly then saw on the wall moving triangles in tge coulour of ver dark sand/ red resembling pyramids or maybe they were pyramids I saw a blue sky and tgere were what looked like white mountains ( snow) on top of the pyramids and there was at there very top a long straight cloud of steam that covered it all and then it went black tgen white then black. The image was about the size of an a4 piece of paper and was like a projection. It was moving like it was never ending only sometimes there were no white mountains. I must have looked at it for about a minute and a half and knew nobody else could see it. Btw it was all like paint it wasnt a real life image but it just came and went . Please im realy confused any possibilities as to what this is??? Im 15 year old muslim from uk.
