Dreams can be strange.....
Galiel's just having one of them. Riding on Rainbow Dash.... actually... even enjoying it! then... waking up, realizing what was going on in his mind while he was sleeping. Sweated and terrified he is comforting himself by saying stuff like "just a dream... it was just a dream" well.... It was just a dream.... wait was it?
