Some strange things have been happening to me?

OK so for months these strange things have been happening to me. First in Textiles cl I had a vision of painting newspapers! Then are teacher asked us to pain newspapers! WTH?! Then I started thinking things in my head and people said them! I would think 'chocolate' and someone would start talking about chocolate! This happened LOADS of times. I would think about it and not say anything but then someonen would start talking about it! Then I went to this theatre place on a school trip with my drama group and everyone got into a circle and I had deja vu! I felt so familar but I had never even been to that theatre before! It was the first time I ever went yet it felt like I had been there before which is impossible cos it was the first and only time I went to that theatre! Since then NOTHING strange has happend. What do you think of all the strange things happening before???
