I have always known a couple triggers of mine that greatly increase my chances for a night terror. Namely the two biggest are heat and sleeping by myself. When sleeping, I now have an industrial fan, ac, and light blankets to help deal with any heat issues. Sometimes this is not enough and when I am alone I tend to have very bad terrors. I also have been known to both talk and walk in my sleep but apparently I will not or can not open doors in my sleep so I tend to stay contained. A lot of my terrors are without a lot of information and I wake in panic with my heart racing, my nerves are shot, my hands shake and I am filled with a need to run and flee or hide somewhere. Every now and then it is more like a nightmare where I remember what the general focus of my panic and deep feelings of depression are.
It is VERY important to start learning what triggers you have. This website www.nightterrors.org has a lot of good information and I advice everyone go check it out.
