Wouldn't that be a huge generalization? Being psychotic means you do lose contact with reality; it's a mental illness.

Being superstitious is different because it's a belief, or practice that results from ignorance, or an unreasonable fear of the unknown or mysterious, morbid scrupulosity, trust in magic or chance, or a false conception of causation.
Superstitions are an abject attitude of mind toward nature, the supernatural, or towards God resulting from such. It is also considered an idolatrus religion.
