What does this dream mean?

I skipped school and was walking down a country lane when I saw this boy I met on holiday (I didn't even know his name) with his family. He was with his dad, mum and "sister" (He didn't have a sister, he had a brother). We were all walking along the road and his dad had a map. I was walking with the boy, who told me his name was Josh (I didn't know his name at this point). I said "Do you remember me?" and he said "No, I've never seen you before in my life!" and I got upset. He kept saying sorry and trying to hug me. Then we went into this building, sort of like a mix between a block of flats and a school. We were walking down the corridor together when this annoying little boy that goes to my school (who likes me) was walking with me and saying stuff. "Josh" was walking with me and a small girl with freckles and heavy eye make-up smiled at him. He smiled back at her and we all went into this room, where people were laying on a bed watching TV. There were no lights on. I said hi to someone in the bed, and he waved at me then said "Shhh!". Then the dream ended.
