          (actually probably material in weird ways)

          That's the key - air, radiation, gravity, all the "invisible" parts of the universe are material. They have material effects that are distinguishable from them not having an effect. Putting gold foil in front of a radiation source will prove radiation's realness as the particles punch holes in the foil.
          One of the key claims of ESP is that it doesn't act in a material way, instead being some weird vibe that nothing can detect except our brains, which are special because reasons. Electrons, neutrinos, even time travelling tachyons are actual, physical objects that exist and can be detected, electromagnetism and gravity will pull objects towards them, but ESP is based on the idea of there being something that doesn't interact with any other part of the universe, but somehow still grants us awareness of other parts of the universe.

          I was talking about, “materialism literally is not about no spiritual stuff existing.” Dialectical materialism, among other things, literally is about no spiritual stuff existing. The Chinese Communist Party to this day is atheist, and while it tolerates religions, its position is that their destiny is to wither away.

      Materialism means we believe in a world that exists independent of our observations. This external world is in dialogue with people. There is not some kind of third thing that's not in the world, not in the people, and fundamentally unobservable/unknowable, like God or souls or woo in general. (See Engels on agnosticism in Socialism Scientific & Utopian.) Either these things are real material phenomena, in which case we can use science to analyze ghosts or whatever, or they're not. There is room in a materialist worldview for like, cryptids, but most "parapsychology" is stuff that requires discarding huge chunks of knowledge. For instance premonitions violate causality. If you give that up, what's left to be materialist about?

          What does it mean to "believe" in something you can't observe or understand? There's a sort of frontier where you make observations, form and test theories, and grow to understand the observations. We agree that crank theories, without evidence and unable to prove anything, are indistinguishable from the supernatural. So what good does it do us to consider them? We should explore things within the frontier - does infrasound cause ghost sightings? if so, does that summon ghosts or change the brain? - on a materialist basis, like some of the fringe scientists are trying to do. Invisible teapots that humans will be able to see in 3000 years should be dismissed as idealism.
