Hi,
Dreams if they were whiter than normal, are from God. Dreams that are also brighter and more colorful than normal are from God.
You said you had a feeling also. That is usually God.
In any event the only one who knows what this means is you, as God normally gives messages only to the person in thier unique way of communication.
The idea of only one habitated planet, is so far, quite reasonable. We have found none other so far, and it is not at all useful to quote statistics and or probability for something that may not exist.
So, it is quite possible, that God showed you the relationship of this planet to the universe.
You said you had peace afterwards. This also is a characteristic of a communication from God to you, on a certain subject if it was a mystical experience from God.
Whether or not it is, God, is up to you to find out. It is discernable with a little work. It is testable, somewhat:
You saw. Thus if God gave the message, He gave you the ability to see this message. You felt, thus God gave you the ability to feel what the message meant.
In order for you to feel more certain, look around in The Holy Roman Catholic church, for any current Catholic mystics, they will see, actually see in their mind’s eye 80% of what you saw, in the dream. That is your test. Do they see 80% of what you saw.
Also, have them tell you of a vision, you will see 80% of what they saw, if your message is from God.
That is my experience when it happened to me once upon a time.
