google,
the best skeptical advice i can offer has already been offered in this thread. but another tool of critical thinking i can point you to is Occam's Razor, or the rule of parsimony. i posted in a similar thread a couple of days ago an example of its use. i think it applies here as well, so i will paste a bit of it for you:
in the case of spooky experiences, a simple mind experiment could help you determine the most likely truthful explanation for the spooky experience. using parsimony:
which of my explanations contain the fewest assumptions?
explanation 1: it is coincidence that i woke up at the moment my dear family member died. (one assumption: coincidence)
explanation 2: there are unseen forces. they work to help us or hurt us. an unseen force awoke me at the moment that my dear family member died. (three assumptions)
explanation 3: we are all somehow connected in the great universe. i was somehow connected to my family member because we were close. when my dear family member died, the connection was severed, or disturbed somehow, and a woke up. (three assumptions)
i hope this helps. fear of the supernatural is an old, ancient way of thinking. our species has a compulsive desire to explain things. when education, knowledge and science were not available to explain natural phenomenon, they still tried to explain it. it kept the tribe together, and fostered faith in the tribe leader. but we're modern. there is nothing wrong with throwing down, letting go of, the explainations our ancestors held to. who knows where we could go without them?
