SLeepwaling Heidi.....

I need help. I been sleep walking for a long time. I woke up this morning in my closet on the floor halfway uder the bed, legs in the closet. Does anyone have any advice, I tried tying myself in, I tried begging my parents to let me have a dead bolt key, gave up on them went to management because of how easily it is to get in here without a key. I'm trying to alert my township about the sleepwalking so I don't get hurt, just by living in front of a railroad trax. Please help me.I need to feel safe again. Heidi
