My favourite bit of TCM is where the girl has escaped from the house and is fleeing from Leatherface and runs into tangled branches. It feels like she is fighting her way through the branches for ages and all the time Leatherface is coming after her but never quite catches her. Another dream-like sequence is when the girl wakes up in the house to find herself tied to the chair at the dining table with the whole family around her and she screams and screams and screams for what feels like a quarter of an hour. The montage is excellent in both scenes.
I've had the same nightmare a couple of times with different things chasing me. Once it was Cybermen from Doctor Who and another time it was Freddy Krueger(s). No matter which way I ran I always ran into them but I always had another way to run, so they never actually caught me. But the chase went on and on and on.
I feel that the best of these films with creatures like Michael Myers, Leatherface, etc. are the ones that successfully create that nightmarish feeling that you are trapped in a chase that can never end but that you can't let the thing catch you either. Laurie is trapped in that chase in the last section of Halloween. Most of TCM is taken up with Sally trapped in some situation or other.
