I used to have nightmares all the time when I was a little boy. I always used to know when I were about to fall asleep and have a nightmare. I'd see this dot in the distant when having my eyes closed that would approach instantly when the nightmare would start, I would also hear a high pitched beep in my ears as if something just exploded next to your ear, which too would become louder and inevitably start the nightmare.
After that I usually had nightmares of giants tracking me down, hearing their footsteps come closer while they step faster, finally they find me and usually kill me in the most gruesome ways. After I explained this dream to my mom I was taught that the footsteps was simply my heartbeat that raced up as soon as the footsteps came closer, I never had a dream like this ever again afterwards. Not only that, I never heard the beep again nor saw the dot.
This wasn't the only kind of nightmares I had, I also used to have the kind of nightmares where my house would shrink or where my mom would take me for a drive and we would just drive into some river, pond, lake or something and I'd drown. Also having zombie invasions in my house where I'd usually kick them down stairs until they came from the attic and I'd die, or those dreams that you look out from your window at the garden and you suddenly see someone entering your garden by opening the gate, grabbing the nearest rock and then start ramming against the windows, inevitably entering your house and slaughtering your family members one by one and leaving you until last. Or this whack dream where I was on this alien wanted list and I was left behind by my family and had to run for my life. Oh and that in every dream I could never speak or shout, very frustrating.
But from the moment my mom told me everything was a dream I kept having lucid dreams , being around the age of 10 you can think up some pretty whack dreams. I dreamed being a Power Ranger, being able to fly, playing on Super Mario 64 levels, being Spider-Man. That was awesome.
Then I came into a depression thanks to school and whatnot more and I barely even dream or remember my dreams nowadays. When I do dream I usually wake up the moment I notice it's a dream. I still have some pretty whack dreams sometimes though.
