Will NOT sleep in her bed!!!

[Nikki234]

My 4 yr. old daughter started changing drastically during bedtime.  She was sleeping in a toddler bed until last June (she was 3 at the time), started getting out of bed and bringing her blankets with her and sleeping on the floor in the hallway right at the top of the steps (there is a gate).  We did get her a big girl bed and it is full size, so I wonder if it's too big for her!  She is still behaving this way.  She is now so afraid to sleep in her room, she cries A LOT when I leave, so I have to sit in her room for over an hour and wait till she is sleeping to leave.  I will then go down stairs for a couple of hours and she might sleep for that time, she might get up and bring her blankets to sleep in the hallway.  In the middle of the night, she will get up and bring her blankets into our room.  She used to crawl into bed with us, but I really put a stop to that!  She now sleeps on our bedroom floor.  I want to change this habit before she goes to school next year!  But I really don't know how to get her used to sleeping in her room!  I have tried just about everything, to soft music, the fan runs because of the loud train that does scare her that goes through our town, to putting lavendar spray on her pillow.  We read a book every night, say a prayer, and sing a few songs.   We even have put a night light and light up fish tank next to her!  I even got her a princess tent to have her sleep in it and she won't!! I think something scared her pretty bad, and remember growing up how scared I was at night.  Our imagination just takes over as soon as the lights go out!
