Dreams and vision are NOT the same. Visions are experienced while awake, while dreams are experienced while asleep.
Visions are LITERAL in their meaning. Dreams are metaphorical...which is why most people do not understand what their dreams are saying.
There are three sources of dreams and ALL are allowed by God:
1~those from God- These are usually about yourself and are instructional, revelatory, or informational about a situation or person given for the purpose of intercession
2~those from your own soul - these types help you to understand more about yourself.
3~Those from the kingdom of darkness-sent to cause confusion, fear, and unbelief; God allows these dreams so that you can have an understanding of what your spiritual enemy is up to...what HIS (the enemy) plans are for you so that you can come against them through warfare.
There are several common dreams that are from God:
Teeth falling out; falling off someplace high; flying; running with someone/thing chasing you; driving or riding in a car (who the driver is, who owns the car and where you are in the car are important.)
Hope this helps.
