Quite a number of times. In one particular dream I found it odd that the people chasing me were finding me everywhere and no matter how well I hid myself. So I began chasing them instead.
Others I would wake up suddenly and be glad it was only a dream.
I have had dreams where I was falling and sometimes I have dreams where I am being chased. I didn't do anything in particular to get away except run. It would always work out okay, and I would wake up safe and sound.
Oh all the bloody time! Too often! No I'm joking, but yes, and annoyingly trying to get away is the tricky bit because my brain knows I'm asleep, so my body doesn't reciprocate when I'm screaming RUN!
