Hard Riddles

When the creeper passes, all the grass kneels

When the day after tomorrow is yesterday, today will be as far from Wednesday as today was from Wednesday when the day before yesterday was tomorrow. What is the day after this day?

When the horse strokes the cat, the wood begins to sing.

Where do you go in through one hole and come out through two holes at the same time?

Where humans breath liquid?

Which button does not function when being pressed?

Which word contains 26 letters but only three syllables?

Whiling away the hours of flowers, Walking through fields of gold. Preening and pruning in lights fading hours, For petals to freeze in the cold. What is it?

White bird, featherless, flying out of paradise. Flying over sea and land. Dying in my hand.

White fat and fluffy, May even look like a puppy. Seems heavy but is light, Floats about without a worry, But if it turns dark you have to hurry!

Who eats a lot of iron without getting sick?

Who is that with a neck and no head, two arms and no hands? What is it?

Who lives in a house with one bedroom, 50 hallways, and ghosts lurking everywhere?

Who makes it, has no need of it. Who buys it, has no use for it. Who uses it can neither see nor feel it. What is it?
