After you die, your nerves and brain cease to function. You cannot feel pain or see or anything. Your simply no longer there.

If the soul has working eyes then it may be able to see things happening on earth or in heaven if that has light to see by or indeed physical things to see.
If the soul has a physical presence then it must be able to feel, the coolness of the flowing waters, the burnyness of the 70 X fire and pitch shirts.

Which as I have mentioned before, would lead you to wonder if you can stub your toe in heaven? Or if you can break your arm? Or die again!
