Mulder is partnered with a young FBI agent, Alex Krycek, in the investigation of mysterious deaths. An apartment dweller called emergency services to report a fire outside his door but firemen arrive to find no fire and the owner dead with a spent fire extinguisher nearby. Scully's autopsy finds that the dead man's internal physical condition resembles that of someone who has been in intense heat, even though there are no visible burn marks. A second death gives them a connection between both men as they had served together in the Marines in the early 1970s. They subsequently learn that a man by the name of Augustus Cole has somehow escaped from a high security facility and that, incredibly, hasn't slept for 24 years. Mulder concludes that Cole is seeking revenge. Written by garykmcd

Fox Mulder: But why Grissom? He was never in country, he wasn't even part of the squadron.
Salvatore Matola: Sure he was. He made us what we are. Him and Dr. Gerardi.
Fox Mulder: Who's Gerardi?
Salvatore Matola: The other Doc. The one who did the surgeries on us. It's because of him... I haven't slept a night in twenty-four years.

I'm not a long time viewer of The X-Files, but followed it up until about Season 3 when it seemed to have changed pace a bit from the early years. I love the villains in the first 3 seasons. So you can measure my taste, among other favourite episodes are 'Tooms'/'Squeeze'/'Fluke'/'Firewalker'/'Home'/and 'Subliminal Message Town' episode.

Sleepless, after searching online best episode lists, is not found among any. This makes me a little sad, since I think this is one of the most eerie episodes. Just the way it was shot and the concept behind it. It's something that COULD have happened...

Do me a favour; when you give this episode a try, make sure it's dark outside and the lights are off. The villain in this episode is one of the best and if watched in the proper environment, can give you chills. His voice, his appearance, his "power". Pure torment. And the best part? It's as believable a far-fetched idea as there is!!! I love horror movies and for some reason, this villain still gives me chills.

Although it doesn't get great reviews, I hope any person reading about this episode gives it a shot. I think it's an underrated episode.
