Personal experience still counts as evidence. If you get a lot of different people reporting the same stuff then that’s a pretty solid indication that there’s some common basis for it.

From this, we know that the physical world affects consciousness in many ways. You can change its perceptions with alcohol. You can make it hallucinate with LSD. You can stop it entirely by applying force to the brain.

So either consciousness is physical or it is non-physical but somehow connected bidirectionally to the physical world. If it’s the latter, in what way is it actually non-physical? If there is some way in which it’s non-physical, shouldn’t that manifest as something that makes it act differently from physical objects? Some force that doesn’t perturb it or some attribute that remains constant when you’d expect it to change?
