Why do bubbles exist?

Why do bubbles exist? Bubbles occur when prices for a particular item rise far above the item’s real value. Examples include houses, Internet stocks, gold, or even tulip bulbs and baseball cards. Sooner or later, the high prices become unsustainable and they fall dramatically until the item is valued at or even below its true worth.
