Thanks for the advice everyone! I never thought of associating pleasant thoughts with the dark, so I'll definitely try to do that.
Also, the next time I walk into a dark room, I'll be OK if I tell all the negative entities to leave? Am I gonna have to do this every time, or will it become unnecessary once I don't feel afraid anymore? And Erin, you say fear attracts them to you...but what happens then? Can they hurt you...and in what way? I don't really know what negative energy looks like or what it does.
I'm sorry for asking so many questions.
