Was this a dream from God? (Christians Only?)?

God does not communicate thru dreams. Only thru His word. Be careful as you have been sent a false vision, either by your own unconsciousness or by another malicious spirit. People can take a dream as yours is and build a whole set of false doctirates around it. And they do, just as Joseph Smith did. God has said everything He needs to say to us in His word. People can misinterpret things in a negitative way and that is why He probably would never communicate thru dreams.
