Indian wells state park, shelton CT

my best friend and i were driving around past midnight and then she decided to show me where her grandparents used to live, down at indian wells. She drove all the way to the abandonned railroad tracks and i heard some faint music box music. That creeped me out so we both decided to leave the area when she saw a black shadow crawling to the right, and as she stopped the car, i saw a girl all white who disappeared after a second or two. I know that this is not our minds playing trick on us, that was nothing like i have ever seen before.
