I remember this when I was young. Seemed scary then, LOL...
A part I remember was the were like 3 or 4 Hooded men, looking down on a normal guy. They looked like they were operating on him or doing something. They all had bulging eyes. They normal guy laying there woke up and was scared, and yelled something like HEY, what are you doing to me!
That is one of the only parts I casn remember. Maybe like early to mid 1960's...
Thanx...
