<s>[INST] Over the past 2 days this has happened to me three times and never before in my life. When I was sitting at my desk once and laying on the couch twice with my eyes open I get a feeling like my brain is doing flips in my head and rolling backward and it almost feels like my eyes are rolling back. It makes me feel dizzy and disoriented until I stand up. Its very hard to describe, but really scares me, have you heard of this before? Iam a 27 year old female.

If your symptoms persist, see your doctor.Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Erion Spaho, Neurologist, Surgical </s>
