It seems that you are very distressed and suffering a lot because of the problem. Your description could be due to several reasons-namely epileptic fit, REM sleep disorder or psychological problem. The good news is that, it appears to be a treatable condition. You may need some investigations to find out the cause such as EEG, sleep study, video telemetry. Consult your local neurologist, psychiatrist or sleep medicine specialist. Best wishes,
