A few years ago I lived in an apartment that was cursed by witches and warlocks. Everyday living there was a constant struggle for clarity due to the fact that they were cursing me everyday. Now that I'm away from the place the curses and demons are not as bad as they were when I was there, but even now I still feel them trying to torment my mind whenever I try to relax via smoking a joint or tobacco. I've cut down my smoking significantly, but they still return.

BTW I've confirmed that it was my neighbors doing it. I don't want to go into a long winded detail about why I believe it, but if you have questions I will answer, just trust me on this one. Also don't say "well no demon or spirit should effect you if you don't allow it." This happens to be a special case where someone happens to be good at cursing people and they struck while I was venerable and didn't have a support group at the time. Prayers help, but they don't close the portals that they're using to come to me.
