I think it was Emerson that said that knowledge is the antidote for fear. The brain is program to pick up on negative things or the possibility of threats. It is like Velcro for negative things and Teflon for positive things. Everyone is naturally more hyper-vigilant at night or in the dark. There is no such thing as being totally safe.
There is a lot of good information at this site. Check it out the tools and skills.
I am not Buddhist but feel like I have got a lot out of these guy's book and website.
