people make shit up all the time and tend to embellish further as time passes.
also, many people will attribute one event with something else because they don't know what the actual cause was.
heaving water pipes, earth shifting etc is often referred to as "ghosts".
People's ignorance knows no bounds is all i'm saying.
when it comes to the intangible, only actual experience will do and even then, as stated, you may most likely be wrong as to what the causality for your transpersonal experience was.
