Why one can't see a ghost?

Why Ghosts cannot be seen?

Ghost is the Soul of a dead living being. Soul is the one which runs the body, just like Software operates a device. Can anybody see Software without Hardware? No, right! So, nobody can see Ghost, Soul (Software which runs the body of a living being).

A Ghost can be seen only when it enters another body. A Ghost needs another body to act.
