It is very common for devil spirits to attack people with certain kinds of "dreams".It use to happen to me all the time, and finally realizing what it truly was, I would wake up very angry, that they took advantage of me in my sleep, and rebuke them strongly in the name of Jesus Christ.They stopped after that.It's not "you", it's "them", and they love to mess with believers in that way. If they can get you to thinking it's just you, they can get you all condemning yourself, for something they instigated.Please check these teachings out, they will really help you walk in the power of the holy spirit, they have helped me very much. http://spiritlessons.com/Documents/Healing/JGL/JGL_Ministries.htm
