The Dreamer

i was in a class room with other people and a friend of mine i dont know who he was i just knew he was my friend. The room was full of photos o the wall and next to me was 4 cameras my friends said pic on up and look through the lens i did and everything beacame more clear. Then i saw him in another chair and he said take a picture then i woke up. Does anyone have an idea what this dream means or represents if you do please tell me.
