I keep having these weird episodes at night right before I fall asleep. They happen in the time between consciousness and the beginning of my sleep cycle. My mind tells me not to fall asleep “this way” or I will die or visit a dimension in which I do not yet belong. Then I have to wake myself up and fall asleep again. After this, I usually have a normal night’s rest. 
I have anxiety but I do no experience this type of dissociation thought the day or at any other time. Only when I sleep. It’s really beginning to scare me and I’m going to make an appointment with a doctor soon. 

Has anyone ever experienced this? What’s happening to me?
