Dream about Peter

A few nights ago,I had a strange dream about Peter.In my dream I was having a party with my family and Peter was hovering por the window,watching me.I walked over to the window and asked him a pregunta ( I think I dicho "why don't tu registrarse us?" But I can't remember XD) and he dicho "I can't" in a sad tone and flew away.Does this mean anything? :)
