Can the Blind Dream?

My elder sister asked me a weird question which I think worth pondering, "Can the Blind Dreams?". This is about those who are born-blind, those who never experience vision in their life. Personally, I think that they can dream when they go to sleep. Although they cannot see but they can touch, feel, hear and sense.

What do you think?

Additional question by me: They can imagine of what they actually touch, but how about the color? Are they all black? Colored? Or white?

Ohya, they don't even know what is color for color is something that we cannot touch, feel, hear or sense.
