A persons lack of belief in spirits is just as likely to sway their viewpoint as much as preconception. Disbelief can actually be a stronger preconception than those who put their faith in a particular version of faith. It is just as blinding to what is actually there. If it is already determined in your mind that you do not believe in such things, than evidence that they do, would be disregarded. Works both ways.
I agree with some of the reasoning in your post (the uknown), partially, CL, but I beg you to reconsider the logic above. Please just go with me on this...
- Each of us currently lacks belief in an infinite number of real and imaginary things. That is how we start life. Lack of belief is neutral ground. It's only as you grow and learn that you build your perception of the existence of other beings.
- Your previously neutral lack of belief in the spirit realm was filled in when you adopted (or were fed) a new perception as a child.... of god, satan, angels, and demons, correct?
- That perception was built upon yet another set of presuppositions: that the Bible is the word of God, infallible perhaps, and that Mom & Dad, and the Society, were instructing you properly from it.
- Now to accurately assess things you must clear out the bias and presupposition that was placed there early in life.
I started the same way as you but in recent years realized that many concepts in the ol' dome were based on a faulty foundation. I peeled away layer after layer of presupposition until I got back to a lack of belief in the spirit realm.
It's not that I wish for there to be no spirit realm,nor would I say it does not exist. I just have no conclusive reason to believe in it at this time. That is neutral and should not influence me to reject EVIDENCE that it exists, if real evidence is ever discovered. On the contrary, I agree with Isaac Asimov:
"I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be."
As for the spirit realm, I do not believe it's impossible, only that it is highly improbable until proven otherwise. That goes for a great many unknowns, including UFOs.
For example, see the thread below... I was initially intrigued by the lights in the news footage. But I had to tell myself that we must eliminate all other options before concluding that the lights were from UFO(s). A brief search turned up something pretty interesting...

Now what you said about disregarding evidence... I agree with that. But unfortunately anecdotes cannot be regarded as evidence. I believe the scientific method is consistent in scrutiny of ALL ideas, impartial, and does not make exception for presupposition. So the spirit realm remains highly improbable for me, such that I will remain skeptical of extraordinary claims until extraordinary evidence appears.
As for your own experiences, I can't say how I'd feel if I experienced something truly inexplicable. The questions would probably drive me over the edge.
PS. My aunt bought me some Smurf toys and after all the urban legends came out, I was scared to death of em.
