People who become blind after birth can see images in their dreams. People who are born blind do not see any images, but have dreams equally vivid involving their other senses of sound, smell, touch and emotion. It is hard for a seeing person to imagine, but the body’s need for sleep is so strong that it is able to handle virtually all physical situations to make it happen.

Okay, I had a philosophical question come up recently pertaining to this.

Think of bats Texas salamanders (why not bats? see here.). They’re blind - never been able to see. They don’t even know what seeing is.  Their species just doesn’t have that sense.

What senses are out there that we as humans do not have and don’t even know of?
