The world we experience is not real?
This is a good candidate for an OP. You should start on thread on this question.
First thing that enters my head is what about moving pictures. You go and see a series of stills flashed on a screen and perceive motion. This is just an example. It is established that atoms are mostly space so what is solidity?
So what do you mean by experience? Sensory perception? Memory?
