Relax.. there's nothing wrong with LD. It's just impossible that it "drives you crazy". If anyone has ever read Descartes, questioning our own reality is the basis for rationnality... Reality Checks are just the opposite of going insane.

And for the weird sounds, they are just HH that eventually will wear out with experience. Nothing to be afraid. LDing and putting attetion to dreams only has benefits : increasing creativity, intuition, appreciaton for beauty etc.. and having fun while other people just sleep
