I remember watching a foreign science fiction movie when I was a kid. It was about aliens who wanted to migrate to Earth to rule it, so they used the bodies of Earthlings as "mothers" to "give birth" to Earth. They looked like Earthlings, but they had a special ability to see through other people's eyes. One of the men controlled his will to create a "wall" in his mind in order to drive away the aliens. When the aliens finally broke through the "wall", they realized that the man had already planted a bomb to kill them...
