Ok I think it was either late 80’s or early 90’s, but it was a movie about aliens or demons i think, and they would inhabit human bodies until the body was no good anymore, then they would like throw up the alien/demon in the mouth of another person if the body they had got to damaged to live on it was like a dark grey looking creature with real thin tentacles if memory serves. but the good alien/demon that was always fighting the bad ones, I think he was some kind of cop or something, had a yellow light that he spit in this dying ladies mouth to keep her from dying.
The Hidden II (1993)?
sounds more like The Hidden than the sequel.
I didn’t remember an alien cop spitting yellow energy into a dying woman’s mouth in the 1st one, but could be wrong. I haven’t seen the 2nd one but thought it might be it because the rest of it sounded like The Hidden.
that’s the last scene of the first movie.
well, sort of. it’s a man dying in a hospital – a father – not a woman. but he definitely transfers his light/life energy by mouth to keep him alive.
