This set has a "5", two "4's", and a sleeper. The sleeper is the El Sauce, Argentina case. What I have on the incident conforms perfectly to the mainline CE2p case piles. [paralysis which leaves when object leaves; light burns; and what might be an OZ effect on the patients at the hospital]. But all I have is a short FSR piece and a HUMCAT entry. Admittedly Ted Bloecher and David Webb list Roberto Banchs as a resource on the case, and he has a good track record in that country as far as I can tell. So, this case is probably a lot higher than a "Two".
The "five" is Claremont NH. This thing has a technological disk hovering close to the ground making a buzzing sound. The case occurred shortly after another UFO was sighted in the same area, though that was unknown by the witnesses. A very wide lightbeam projected from the bottom of the craft; the male witness said that he felt that the lightbeam had a "solid" look to it. The CE2p effect in the case is not particularly spectacular: the couple's children were seen to be having a fitful sleep, and their dogs were whimpering throughout the experience. All of that could conceivably be related to the rising sounds that the object was making. Still, the fact that another person also witnessed an object at the same time makes this a strongly credible case.
Both of the "fours" are quite odd. Hemliden Mountain, Sweden: The director of a transmission facility in the mountains heard his alarms go off and looked outside as part of his investigation. There he was confronted by a 150' wide object with a "tunnel" in it. Around the thing were many four-foot-on-a-side fuzzy "cloud-colored boxes" apparently doing something. At this moment the director realized that he was paralyzed. 6 or 7 of the boxes then floated by him into his facility, apparently inspecting the place. In 5 to 10 minutes they came back out, entered the tunnel to the ship, which then shot off to the north. At that time the witness regained the ability to move. The reason that I rate this thing a "4" is that it was published in the Nordic UFO Newsletter, which I consider a small unknown gem in old UFOlogy. Things published there have had an aura of seriousness about them that I don't find in all publications.
Lastly there is the Strange-to-end-Strange case of "Dr. X" in southern France, a case which shook Aime Michel and overpoweringly influenced Jacques Vallee. To say the case is complex doesn't do it; you should read it in detail elsewhere. For our purposes we can leave it with this: A professional medical man sees two objects creating very bright light pulses. These two objects merge into one. This thing points a beam at the witness, then tilts in the sky and vanishes [one gets the impression that this is a very fast sort of vanishing rather than a "poof" vanishing]. The doctor finds that a leg injury is now healed, but he has a triangular discoloration at his navel. Astoundingly, he says that his young son also acquired the same mark, despite not having been where he should have been exposed to any beam. After the event and over much time, many paranormal claims come from this doctor, including poltergeist phenomena, recurring twinned triangles on his and his son's navel, patently impossible electrical flows through broken equipment, and the doctor levitating occasionally. Well, even open-minded me, would dump this thing in a flash if it were not for Aime Michel saying that this guy is a person known to him. But, since most of these later claims conveniently never happen when anyone can see them, I still have VERY large doubts. I can't get any handle on this one at all. In honor of Michel I compromise with a nervous "four". Below is a not-completely-fictional cartoon version of the UFO part of the tale.
