Epilepsy helps. Most definitely. I understand certain migraine disorders are closely related enough to induce travel, ha ha. Though neither disorder is necessary. A certain Peter Pan type quality and certainly an astoundingly obstinant imagination with which one can ignore all reality would suffice, I’m sure. The belief in any spiritual, unscientific mumbo jumbo is entirely superfluous, as this simply calls for brief and momentary willingness to suspend disbelief (and if you can watch any film and forget for five minutes where you are, then you have already achieved this). This is possibly akin to meditation without the try-hard factor. I highly recommend!
