A man named Sergey Korovin a local resident reportedly disappeared for 5 days, appearing later in the town of Pervouralsk. He was suffering from complete amnesia but due to his passport, which he carried in his pocket he was able to return home. He did not recognize his wife and children, and his only choice was to start "all over again". He told the militant men, relatives and his doctors that he could only remember lying on a couch inside a room that somehow resembled a hangar, and several small luminous entities walking around him. He said that the entities "looked like humanoids from science fiction movies". He remembered the moment when he was lying completely powerless on the grass at the outskirts of Pervouralsk and seeing a disc-shaped object ascending to the sky over him. The disc was circled by a row of bluish lights which dimmed and brighten at intervals. Medical doctors including his psychiatrists agreed that Sergey was quite normal and had suffered some type of psychological trauma. Apparently most of the memory of his abduction and some of his family memory was erased from his mind.
