It is true. Some of us have seen things and dreamed things since before Trump and during. Dreams are a form of vision and visions comes in dreams, be they waking dreams or nocturnal dreams.

Discernment is a big key and of course are always false prophets except, I think they use much cruder means, TV etc. etc. So they are easier to spot! ;)

There are false visions but when you begin to know you own mind, your filters should be faster and you heart the final filter and knower.
