It is possible to shift that with meditation, it can be used as a way to sort of train yourself to focus attention on different things. I'd say it's a bit like if someone tells you to "make yourself heavy", you can't literally change your weight with your mind but you don't consciously think which muscles to relax and so on either, you just sort of... be heavy. So you can try to "be in your foot" and think about how the other parts of your body are moving around that instead. I've had it click sometimes but it promptly surprises me out of the state.

Also with meditation, psychedelic/dissociative drugs and things like sensory deprivation chambers, people sometimes experience complete dissociation where their awareness is fully outside their body!
