What beliefs would we consider reasonable for a self proclaimed Christian to hold?

[Angrboda]

A few bad apples is not a good defence. Scientists have had failures too. Just saying.

What kind of a response is that? Are you suggesting that some OBEs are fake but that others are real? Based on what? They appear to be the same phenomena, the only reason you want to suggest otherwise is because concluding that they are all hallucinatory is in conflict with your argument. That's not a reason to believe there is a difference between hallucinatory OBEs and those for which it's an open question. This is just wishful thinking on your part.
