Lucid Dreaming and OBE

I am new to this forum and wanted to speak to someone as to the above topic. I feel I had an obe once and also a state of no body awareness. There are times that I know I am dreaming and want to wake up so I find myself screaming in my dream yet nothing is really coming out. My husband thought I had lost my mind when I woke up in a panic and asked him why he could not hear me screaming his name to wake me up and he said because you were not screaming, you were sleeping. Weird feeling. I have also had an obe (I think). I was feeling extremely tired one night and at the time my two children were 3 and 5 and wanted to sleep with Mommy while daddy was away. I put them to bed earlier and when I went to bed, I crawed in between the two of them. I layed down and noticed and weird shadow outside my window. It looked like a tree, but I knew there was no tree outside the window. I got up and went to the window to peak out and there was nothing there, but when I closed the curtain, I saw it again. Having a sense of protectiveness I decided I would go and check and make sure all the doors were locked again but when I reached the door to the bedroom, I flipped my light on and nothing came on. I thought that is weird, so I decided to walk out into the hallway, but found I could not. It was like a force field was keeping me in the room. I also noticed a buzzing sound the entire time, but figured it was because I was so tired. I happend to look back at the bed to check on my children and because of the light coming in from the closed curtain, I saw me and my two children lying in the bed. I was not scared, but just confused but something told me to just go back so I slowly climbed into the bed and slipped back inside myself. I woke up fast but my heart was racing and I was in so much fear. I jumped up and went to the door and turned the light on and it came on. I went out the door as normal. Very strange feeling. Can someone help me with this?
