This is something i believe to be very underestimated by many as is the shock that so many would face with a first time sighting. Seeing one of these things for the first time would really affect many people, even ones that would think they would be more mentally prepared than others. Self confirmation of the existence of this animal via a sighting and the huge mental toll that it would take on someone is very real, especially if it isn't deemed to be on completely friendly terms or isn't in a situation where you feel completely safe.
