Any ideas what this dream means?

The dream: I somehow met this family who had one child (about age 11 or 12) with mild autism, in summer sometime. They asked me if I would like to basically hang out with him and help him with everyday things like cooking when they were away. He was very nice, and in the dream I think I had known him when I was very little (about three or four) even though I had never known someone with autism at that age. We got to be very close. I think. I don’t remember much, but I remember one scene where his family and I were in their attic, looking out at the snowy forest (there was a big window). The attic was somewhat cluttered but very well furnished (like a living room would be). There was a fireplace. We were planning to go skiing.
