What is a soul? Really...

"You don't have a soul. You are a Soul. You have a body" - C.S. Lewis

Let's assume that the above statement is pure fact. When we die, we, as souls, supposedly leave our bodies. Let's also assume this as fact. Our bodies possess five basic senses: sight, hearing, touch, smell, and taste. There are other senses but let's just stick with these five that we are most familiar with.

Since we discard our bodies upon death (or upon astral projection or something like that), it is only logical that we also lose input from our five senses. Moreover, we also lose our ability to think, since our brains are part of our body. So if we leave our bodies, what would we feel? Or better yet, what would we sense? Or even better yet, what would we be thinking?

We only gain an interface in the material world as long as we are connected to our bodies. If we lose our bodies, it would be like a computer without any peripherals. No monitor, speakers, keyboard, mouse, RAM cards, processors, etc. So basically, we're just left with just the motherboard. How on earth can you operate a computer like that?

This concept conflicts with the idea of reincarnation wherein memories are passed on with the soul from one body to another. Memories are stored in the brain, and the brain dies and decays with the rest of the body.

I think that the bare soul alone is conscious somehow. It is a mere consciousness that can't see or feel or even think. It just exists and is conscious; it's some sort of strange energy.

Some stories (including the bible) and especially some emo sayings state that a soul can be inflicted with pain and suffering. If that is the case, how exactly? I guess it would be a pain in the... uhh... consciousness?
