Yegorov Alien Monkeys

The Yegorov Alien Monkeys were sighted in Inner Mongolia in August 1945. They were sighted by a Soviet fighter pilot named Vasiliy Yegorov who got out of his ship before it crashed. He laid down in the brush and fell asleep, only to awake being unable to move his arms or legs. He lifted his head to see he was restrained by semi-transparent tape and around him was a sound like twittering birds. There were hundreds of small monkey-like humanoids holding knives that took him away. They stood 45 cm tall and lived in underground mazes. They claimed they were a part of the “Khanyangi” tribe. He lived among these creatures for years, being found in 1959 above ground by cattle breeders during a thunderstorm. He had been presumed dead and no one believed his story, though X-rays showed a trepanation (a hole being cut in the skull and that piece of bone removed) with this being 15 years old.
