I am 24 and I have these dreams since I can remember (4-5 years old). I dream that somebody is following me, then chasing me, and when he finds me I paralyze in fear, and I can't move at all. Every time I dream this, there are other personages, other circumstances, different motives, and he never catches me, because the dream is so extreme, it wakes me up. When I was a kid I was so scared that I woke up sweating, and my heart almost exploding. Now I got used, and at the end of it I realize I'm dreaming, and I think about something else, and change the dream with a better one.
