True. However, he doesn't mention dreams he rejects as plausible or valid--at least not without explaining why he rejects one. But I've never known him to post a dream of anyone that he disapproved of. Actually, all the dreams he's mentioned are similar to his own or his wife's as I understand it.
Individuals attempting to disclose information will sometimes use a vehicle or poetic license, by which I mean they have received sensitive information too dangerous to directly disclose. They may claim to have had a dream or vision, or to be a time traveler (John Titor), or aliens-reptilians-shapeshifters (demons/Satan), or even the highly developed Illuminati Card Game. I don’t know about Praying Medic or whether or not he had a literal dream, but I am just saying he might be exposing a plan or sensitive information someone passed to him as the plausibly deniable ‘I had a dream’.
Joel 2:28
28And afterward, I will pour out My Spirit on all people. Your sons and daughters will prophesy, your old men will dream dreams, your young men will see visions.
