Is this for real?

I wonder is this for real, I mean I saw the police station and me going to it with one of over teachers Mr. Upul and saw the entire thing. and also I saw that two people telling me about there was a teacher who was the best in Sri Lanka working at school when they were studding. I went to my sisters house for her daughters birthday and I told her about a this stupa

and told her that I have seen the roof somewhere but 1 of march that I went to see kandy and with that the gagaladeniya and I saw it then the pervious was a dream I have seen this two pictures months before

 

how could this be possible some of the things that happen and said to me by people after few minutes I remember them as I have seen them in a dream. why is this happening to me  and I am the only one experiencing this.
