eyelash growth

so over the past few months I've had many dreams which all seem to be based around the same things but there's never a set pattern of events or specific story as to how they come about:

-Teeth falling out to the floor, into my hands, twisting and becoming loose where i would be constantly trying to fix them, often the scene is where im looking in the mirror when this happens or just standing in my room;
I did have my braces taken off around 2 years ago and now wear a retainer most nights and did have many adult teeth taken out prior to the braces.

-Enlisting and enduring training and actual operations in the army/naval/airfforces, sometimes with friends, i have had one or two dreams where i've actually carried out missions killing in the process (quite gruesomely), sometimes an everday situation where i might be in a shopping mall turns out to be some sort of attack?;
now this may just be my own mad imagination i do play alot of cod and going into training for the experience is something i am considering (haha)

-hair loss of some sort, the most recent being where my eyelashes had fallen out/i had pulled them out accidently all from one eye, vaguely i can remember i think i also had fake eyelashes

people have told me its something concerning my health, im worrying about something? or particularly with the teeth i may experience or be experiencing a loss of some sort, any other explanations or alternative ideas on these scenarios would be much appreciated thanks

feel free to tell me if im just being silly or overreacting to these!

i would go see a doctor or a shrink cause this could be your body telling you your having somesort of medical problem
i dont think cod has any thing to do about it lol i play cod all the time ive never even had a violent dream
