I almost never have dreams like this. Last time I had one was like when I was Yr 3 primary school(ages ago). It was a short dream where I was running from a monster disguised as my dad... He had a really scary expression. "Dad" was chasing me in a car. I was running so hard so it took a while for him to catch up. When I got caught I woke up and I screamed. It took me a couple of seconds to register that the dream has ended.
