Sleeping with a baby blanket

I live with my friend and she is back at travelling abroad for work so I’m alone in the house. When she is in the house, I get a break from my sleep disturbances (nightmares, flashbacks and shallow sleep stops).

Now that she is gone my intense night terror has comeback. The first two nights after she left was awful. I barely slept. I’m not even quite sure what I’m scared of because I know I’m in a physically safe place. I found her son’s blanket and started sleeping with it and it is the only thing that makes me actually feel safe. It’s so strange but it works. I can close my eyes and soothe myself to sleep now.
