I Have Been Experiencing Many Incidents Over The Last 6

I have been experiencing many incidents over the last 6 years that have affected me in ways that are unexplainable and scary. Like sleep deprivation, walking in my sleep (almost burned home down 3 times), psychosis, out of body experiences like talking to my subconscious. Find myself in different parts of home and not know how I got there. Dead weight falling injuring myself. Falling down stairs breaking ribs. Constant vivid crazy dreams and wake up screaming and crying and takes hours to get over it or get myself back together. Living in fear and having panic attacks out of the blue. I don't think I can take much more. Need help. I am retired Navy and have experienced a lot of death in my life. Sleep in 20-30 minute increments. etc..etc.. Help
