it is interesting that in many cases it is experienced by musicians or people who listened to music just before, during or after, from what i can gather - maybe if the percentage of them is high enough, there could be some connection or something that gets activated

re the author's experience with flying cars, wouldn't really fit into pure ffd syndrome as described here. but more like clairvoyance like da Vinci, even speckles would fit in there, from most descriptions

i think it would be hard to cherish those experiences however great and unusual they are extremely frightening and most of the time useless

anyway, great series and great ending of this research
