I've been having weird dreams were I die one way or another and also random , last night dream they cut off my head and put on another one, but somehow I took it off and put my head back on..
interesting... could it be that you are taking on too many persona's (you are wearing too many masks in order to fit in with society)? You may be letting yourself think that these persona's are you. They are taking the place of you discovering your true self. Who is cutting your head off? Tell me the other ways that you are dying.
Your user name says it all - that you will adopt a new philosophy in life (cutting your head and putting on a new one), perhaps many. The many random and constant deaths show that your ideology is a work in progress, that it will likely change according to audience and circumstance (like school, business, different friends.) You seem to be on the path of a seeker...
