Sorry you had such a disturbing dream. I was reminded of a lot of stories? Alice in Wonderland and the small doors/size thing, Medusa, who would turn people to stone if they were looked at, and who, herself, had her head chopped off by Perseus and used as a weapon against others? Too, there's the Snow Queen. You been reading any such stories or studying them in school? The Tony's were on last night or the night before, were you watching them, they had some good music. That would be a premier music performance reminder I'd think.
