Wierd cbt therapy

[caza01]

Hi. I'm currently having cbt therapy and during the session I felt like I was unconciuos then opened my eyes for a couple of seconds to myself having these involuntary movements of the head and shoulder. I believe this to have been a seizure.

After a couple of seconds I was out for the count again. I have asked my therapist about this but she says she didn't see anything. Can this all be my mind playing g tricks although it felt so real . I'm driving myself mad. Please help
