Dream About Long Hair

Hello, Rabbi, I dreamed in the early hours of Shabbat that I had long, straight hair, and someone curled it so that it would look prettier. I woke up really frightened because I had heard several times in the past that long hair in a dream indicates judgments and great danger. I was afraid it was forbidden to fast on Shabbat, so I did not fast. Would it help to fast on Sunday, or does it have to be immediately after the dream? Besides that, what else can I do? I am really scared. I would appreciate a quick response. 

Thank you very much.
