(It's all canon to the series.

The characters are all stil friends.

Dream has a twin called Nightmare,who is basically a red version of Dream himself and also controls him sometimes.George is the shortest of them all)

Everyone was in the forest, hanging out with each other.

George,Sapnap and Dream were a bit away from the others.Sapnap and George were chasing after Dream,trying to catch him as a joke.George was slightly less faster,so he remained behind while Sapnap was faster and was nearing Dream.He almost grabbed the back of his hood when Dream made a shift all of a sudden.Sapnap bumped into a tree and Dream accidentally did too,which resulted in Sapnap pinning Dream against the tree unintentionally.George got to them and stopped running, looking at them both shocked and akward,because he and Dream were a couple basically and seeing this,he felt a bit jealous,but stayed quiet.

(you're Dream and male.)
