How can someone have any conscious thought, feeling, or any sort of perception of their external surroundings without a functioning brain and central nervous system, not to mention the absence of the other sensory receptors of vision (eyes), sound (ears), smell (nose), and taste (mouth, tongue, and tastebuds)? I have yet to receive an answer.
The answer is actually quite simple. According to Christian beliefs, your soul consists of a physical body and a body of spirit. The spirit has all that you mention and simply detatches from the body. People who have near death experiences nearly always mention that they still have a body that appears to be very much like their physical bodies. They can see, hear, feel, think much like they did in the flesh, but without the limitations. One, for example, said that on Earth one could look at a toaster or an electronic organizer and not know much about it. But without the flesh, just seeing something opens up all sorts of knowledge. One not only knows what its for, but how it's made up and how it functions. I personally think we existed prior to taking on our physical bodies. It's said we are made in the image of God, which raises the question of why God has an image with all of our physical properties. But that's another topic.
