How do Muslims discern genuine spiritual experiences from hallucinations?

When believers appeal to their private spiritual experiences to argue for their faith, skeptics typically respond by dismissing their stories entirely, conjecturing that these are more likely cases of hallucinations, some form of mental illness, or simply their minds and emotions playing tricks on them. How do Muslims make sure this is not the case? How do Muslims discern genuine spiritual experiences from hallucinations or 'mind tricks' in general? **Note**: this question is inspired by a [similar question](https://christianity.stackexchange.com/q/86124/50422) recently asked on Christianity Stack Exchange. ______ Possibly related: - https://islam.stackexchange.com/q/64219/42469 - https://islam.stackexchange.com/q/68840/42469
