The Vikram-Betaal stories are derived from the Vetālapañcaviṃśati (वेतालपञ्चविंशति) or famously called,
Baital Pachisi ("Twenty-five (tales) of Baital").
Do these stories find any kind of reference or allusion to, in any form whatsoever, in the scriptures? Or should they be only considered as local folkloric tales ( दंत कथायें ) and cultural stories, in line with the stories of Singhasan Battisi?
Also, is Beetal some kind of or a class of some supernatural entity or creatures within the Hindu pantheon?
