Experiences are best described as the collection of things a person has done.

Explanation:

In fact, experience is a form of direct knowledge, acquired through the collection of things a person has done during his or her life. Experience is true knowledge, which neither requires nor involves belief, for knowledge precludes any need to believe.

An interesting example is the fire analogy. If you put your hand on the flame you don't have to believe in pain, you don't have to believe in pain for pain to appear. The pain is experienced. It is immediate, direct, and it comes with an intensity that anticipates intellectual beliefs and interpretations. So it leaves belief in the background. When you put your hand in the fire, you don't have to believe in pain for it to exist, the pain comes right away when you put your hand in the flame, the pain comes before the mind prepares your belief or questions about it.
