Tell me what you think.
For what is that thought, but immaterial.
The report is itself proof of the immaterial. Not just by the dream-like images reported, but by the fact that the report itself is a thing of thoughts immaterial projected onto pixel and ink.
But that same argument applies to lightning. I can't prove that every--or indeed any--lightning bolts are not in fact thunderbolts being hurled by the hand of Jupiter/Zeus/Odin. And that's emphatically NOT a glib comparison: the major civilizations of the West believed that to be the literal truth, for at least as long as Christianity has been around. You cannot prove them wrong.
For that matter, the argument applies to disease, incontinence, gravitation, peristalsis, hair growth. Sure, material explanations exist, but that doesn't rule out magic.
For what is that thought, but immaterial.
Pattern of material. It exists, but not independently of a material instantiation in a brain, a computer, or a sheet of paper. Mickey Mouse possesses immaterial reality in exactly the same sense. Forgive me for not questioning my reason or bowing down to worship in the face of such examples.
