Besides, how far are spiritual people from physicists? If we can imagine wormholes and 11 dimensions, why not the mind as an entity contained within the body but separate from the physical?
My question, "how could a non-physical mind influence a physical body?" is very different from the questions you've compared it to. Your question, "how can one person influence another?" is not a problem. I could give you a black eye by punching you in the face; you could make me happy by smiling at me, etc. If we had to, we could conduct experiments that would provide very strong evidence for my punch being the cause of your black eye, or your smile being the cause of my good mood.
But the same cannot be said for claims about the influence of a non-physical mind on the physical body. Because minds are supposedly non-physical, we can't really investigate them in the way that science investigates physical stuff. We can only guess at the nature of spiritual entities, and that seems to be exactly what spiritual people do. If my emotions are in my mind, then how could my anger cause me to punch you? How could something that is not made of matter have any causal influence on something made of matter (my body)? A lot of spiritual people will say, "I don't know. Spiritual things are just beyond our understanding." But then they are claiming to know that spiritual things are beyond our understanding! How can they know this? Isn't it just as plausible that spiritual things actually don't exist, and that's why we don't know anything about them?
Your question, "how can a person feel hot or cold?" can be answered by Physics. Look it up on Wikipedia. Your question, "how can a person feel pleasure or pain?" is a problem for you, Mr Dualist. How can some spiritual entity make us feel emotions?
Physics is completely different from Spirituality. Physicists use scientific methods to gain knowledge of physical things. Spiritualists don't do that. That's quite a big difference!
The difference between imagining wormholes and imagining a non-physical (and therefore non-spatial) entity, which is located in the body, is that there are mathematical/scientific reasons to believe in wormholes. How can something non-spatial have a spatial location, anyway? It's logically impossible. I don't know much about wormholes, but presumably like every well-respected scientific theory, scientific evidence points towards the existence of wormholes.
Maybe gravity is a better example. The difference between the theory of gravity and the theory that the mind is separate from the physical is that there are mathematical and empirical reasons to suppose gravity is real. If you can show me similar support for the theory of an unphysical mind, then fair enough. But you can't, and until you can, gravity is going to be a more plausible theory than dualism.
I hope that wasn't too long and rambling.
