Hello Jolie.
I have the same symptome at times with panic attacks.I have actually had to limit the time I watch TV at night since I have flashbacks, and it helps not ot have them as often. I listen to music instead after a certain time of the evening. I stop watching TV at least 1 hour before I retire for the evening and belive it or not it helps.(Something so Simple).
I hope you cnsult a professional therapit that may be able to give you more tips to help control the anxiety. Take care and good day. Soidhonia
