RECURRING NIGHTMARES-available for 1on1.

Hi,Greetings.I am perfectly healthy physically with no medical condition as i work for fitness industry.Briefly,I am a very positive person,always happy and i cheer up,encourage people around me to push their limits.I donot thing i have influence of any kind of movies on me as i watch only which interests me.So coming to my issue,as far as i remember,i used to get nighmares past 2years.The kind of dreams i get are very scary,as in,i am being killed,tortured, or assaulted.Almost every night just a while after i sleep,i jerk and wakeup with a feeling that i fell down from height/somewhere where there is no fence.I sometimes feel like i shout for help,cry in sleep when i face a threat but no matter how much i try i couldn't move my hands or legs in the dream.Unsure if this is something that i should be concerned about! Stating a recent dream of mine below. That i was alone in the house and some technician came for repair and took advantage of that situation and tried to assault me.
