Test the spirits.

This is a warning. Dark forces work to lie to you. In the void, dreams, spritual rely etc. God is not very straight forward when it comes to spiritual experiences. He tells you to test every spirit. The one different between a dream from God and one from the devil. Is that God will only come when invited. The devil will force its self on you. Think of sleep paralysis, that is a sign the devil is after you. Wispers and seeing an event would be from God. So test all spirits you come in contact with.
