Bill Wiese backs his experience up with bible verses & the funny thing is someone else who also went down to hell saw the exact same demon as him. i don't think it was a dream. it doesn't sound like a conspiracy either.
Jonah, from the bible, also experienced hell.
Jonah 2:2 >>>
And said, I cried by reason of mine affliction unto the LORD, and he heard me; out of the belly of hell cried I, and thou heardest my voice.
