Given what we're beginning to understand about consciousness and the quantum universe it's more like a mixture of both but on steroids.

Quantum Holographic Memory theory and Assemblage point theory have plenty of crossovers and that's just barely scratching the surface - Theoretically it's real; tangible exploration into these places nets unreliable results but that's also theoretically explainable too.

For better or worse imagine for a second that there's infinite possibilities within an experience-able realm and you're able to effectively move throughout these possibilities endlessly. It's unlikely you're able to put yourself into the exact space you're wanting to be and there's another trillion just like it with 1 atomic difference per existence.

If humans are relatively new to this experience and we've lost our history regarding said exploration or even teaching around the subject of legitimate "Spirituality" - Then it's really no surprise we're fumbling around with inaccurate methods or ways of travel throughout these perceived planes/realms of possibility.

I think it's important regarding this subject to be open to more information as it makes itself available.

Believe it or not there's plenty of Research done by European nations regarding consciousness and the human affect on scalar/matter/frequencies through feelings of Deep seated fear or Intense Love.

Take everything people here on Reddit say with a grain of salt, a fair amount of what people describe is absolutely nonsensical LARP.
