Resting our hearts on the Lord will deal with our subconscious, give us peace, and in general give us good dreams. I have heard of people who have had dreams of something happening to a loved one or something similar which actually happened. This is rare, but certainly God is able to do this, but more often than not such dreams do not come true and are usually the product of inner fears or worries. There is also the possibility of a demonic cause of bad dreams, but generally such only occurs if one has been dabbling in the occult. I have heard of people experiencing horrible dreams when they have gotten involved with drugs, the occult, Ouija boards, and seances, etc.
Terrible things can begin to be experienced as a part of demonic influence and harassment.
In such cases the only way to stop this is to turn to Christ, confess this as sinful, reject it, and turn from it by a positive pursuit of knowing and walking with the Savior. All rights reserved.
