Of the additional symptoms reported in the reports, it is relatively common to mention severe headache, sometimes lasting several days after UFO contact. This was the case with a 15-year-old boy in Brazil, who watched for several minutes three undersized UFO-navts disembarking from two vehicles and talking about something among themselves before looking at both vehicles. After the UFO took off, the teenager had a severe headache that lasted for about five days, no medications helped the teenager. In this case, we can also talk about the effect of microwave energy: there is evidence that microwaves do cause headaches, as was shown in the works of Milroy and Michaelson in 1971.
Very rarely, UFO observers have reported partial or complete loss of vision. In this regard, the case of a 37-year-old US citizen residing in Pennsylvania is typical. For twenty minutes he watched a large disk against the background of the moon, as a result of which his eyes ached, his vision became blurred and gradually he lost it completely. The vision was fully restored (returned to normal) only after a few days. It is known that the human eye is very sensitive to microwave radiation, which is easily absorbed by the liquid inside the eyeball, and as a result, the temperature of the liquid itself and the eyeball as a whole rises, and this can cause cataracts of the lens of the eye, or clouding of the intraocular fluid itself.
In addition, his entire skin was burning, as if as a result of a sunburn: in all likelihood, the victim received a kind of "burn" by microwave energy absorbed by his skin.
In addition to these purely physiological reactions to the impact of UFOs, there are many facts in the reports that indicate that an encounter with an object in itself is a huge shock for many observers. People can unconsciously fall into a hysterical state, they can experience unusual sensations in the form of heat, unusual smells and tastes, they can daydream, while experiencing phantasmagoric visions. All these reactions to stress are of purely psychological origin and should not be confused with the direct physiological effects discussed above.
