I don't require proof just something. For example people once thought OBE's were sure signs that there is a soul or that the conscious of a person could leave the body. But now we have a heap of evidence to suggest they are hallucinations. Before learning about the evidence I thought it was evidence that OBE's were real too, SWIM had even experienced OBE's. But once strong evidence was presented that they are hallucinations SWIM believes it until something shows otherwise.
