How late are you up watching these things because I think what you are experiencing is directly related. Something of course must be triggering these thoughts but they are not 'new' or foreign to you. I know I get repetitive night time thoughts about prior experiences - especially those that have occurred late in the evenings or had a powerful impact on me. They race in my head waking me up. I swear they are real at times and then I realise I am just recalling something I had previously experienced or seen.

I also am curious about your sleep hygiene practices. Poor sleep hygiene can contribute to what you are describing.

In other words, what I am trying to say, is no you are not crazy. There are possible explanations for this.

My psychiatrist has me now taking a big dose of anti-anxiety medication at bed-time and I have yet to have such experiences since.
