From my experience, dreams are not exactly reliable sources of information. Dreams most often occur in the astral realm, where truth is very limited and deceiving forces are very abundant.
Discernment is always key.
Sometimes dreams can provide higher messages for us, sometimes they can provide deceptive messages. Truth is found in our heart beyond all the matrixes and beyond our pre-conceived beliefs... truth is deeply hidden unfortunately under the darkness... we must shine the light to really get to the bottom of it...
Interesting to note... as we make progress in consciousness, we will be given both a true and a false teaching whenver it is time to come up higher. It is up to us whether we are ready to surrender a belief which is false and come up higher in truth, or whether we wish to have a limited ego belief solidified with a false teaching rather than surrendering a false belief and coming up higher with a truth teaching we have been presented with.
That keeps the game firmly in 'free will' territory. If you are given a truth, you will also be given a non-truth to keep you where your at. What do you choose? Do you want to come up higher? Or do you want to continue down the more limited track that you are currently on? Your choice, that's free will.
If you wanna look at it like earth's a schoolroom and it's a test, that's another way to look at it. Your being tested all the time on the path of consciousness on the search for truth. Are you willing to come up higher? That's always the question, you always provide the answer.
Another one: you'll never be given a test your not, on some level, ready to pass.
Anyway, thought I'd throw that out there.
Further, sometimes a lesson can be at a certain level for us, but be at a lower level than for someone else. For example, if we don't believe in God or Jesus whatsoever, than a dream such as the one described can help connect us to Jesus and a higher spiritual reality. This is a good thing, but it will not take us all the way, because there is so much more to go to get to the truth that will set us free.
So all yah gotta do is say "Jesus is Lord" and you're saved huh? And if you don't then uh oh for you huh? Is that what Jesus was teaching?
Or is that what human egos decided was his message when they created many outer rituals and establishments around his message when they ignored the part that said "take up your own cross and follow me into life eternal, the kingdom of heaven is inside of you and it is at hand here and Now, and the truth will set you free. You will do the works that I do, only greater works than these you shall do".
P.S. I agree very much there is power in names. Jesus Christ, which I believe is his ascended name, should be called on and he will be very helpful, including protecting you and your family in et encounters scenarios. Keep Jesus close to you at all times if you feel comfortable doing so. He is love, he is infinitely more powerful than the dark ones. I would suggest that he also is your older brother and wants you to follow in his footsteps
rather than put him on a pedestal like a golden calf. I think he came to help you remember how special you are rather than show you how special he was...
