Hello, i am new here

. But i am glad that i found this place, maybe i can find answeres to my dream what i saw today. I don't remeber it very, but can remeber important things to me.
I was in a high building or something, there was wide balcony. Humans standed there, and traveled with some kind of flying thing what stopped there. I stepped one of the flying thing, and sat down on chair or something like that. Then there was a man, unfamiliar. He had beard, like he had started to grow the beard some days before. Well i talked to him. He said that "i have been watching you" I was suprised, he was very mysterious. He showed me a picture, where i was sitting in class, i was like in 1 class, he showed it to me, like to prove that he has been watching me. I was suprised again, and i asked : "how?" , he answered something, that i don't remeber. Then i looked at table, what was in the flying thing, there was some things what started to move suddenly, i was scared and pointed there with a pencil, but the man just sneered.
well then i woke up. What that dream means... i just can't forget what he said in this dream: "I have been watching you"
I am sorry when you find mistakes, because my first language isn't english.
