Demonic? You're gonna tell me that ESP is demonic? Well, how about color,taste,and smell memory? LOL
Psssssssssssst...there is nothing demonic about this stuff.It's all just abilities that most people lost through non-use.
I don't know how much or what is dormant God-given-to-everyone sort of capacities; how much is demonic and how much Holy Spirit--ESPECIALLY when someone doesn't have a close relationship with God.
I believe all 3 are likely to be factors that would explain some sorts of things--Not together--I don't believe Holy Spirit associates near demonic activity at all--that is--Holy Spirit is not about to have someone confuse who THE SOURCE is.
I expect God to make such things clear in eternity.
I do know that many supernatural things have a demonic association which masquerades as good for seductive purposes that only become clear years later.
