How can you tell whatever experience you had was in fact "real"? Might it be "real" in your mind only?
In the history of human history there has been zero evidence of spirits and the spirit world...there was even a million bucks on offer to prove it and no-one collected it.
I know people who have had spirit experience yet it is not proof...it may have been a dream, it may have been mental illness etc but it was not real at all.
There is no spirit work or spirits because there has been zero proof to say there is in human history.
You can't use your experiences as proof...as they may have been real to you when in fact they are not real.
