I do not know when I had this dream exactly (as in the date or my age), but I know that I had it when I was a kid; and so this dream is very old.
This dream was one possibly one of my first dreams to ever have aliens in it, I have had spaceships/UFOs in dreams before, but aliens are pretty rare or they were rare back then.
In this dream I was outside alone in my parent’s yard during the day, and two small Grey aliens (the common stereotypical type of alien) started chasing me around the outside of the house in circles; but I do not remember where they came from and I do not know or remember what they wanted.
Fortunately they were slow runners, in fact, they were so slow that I almost lapped them! 😀
I was very scared but when I realized that they were very slow, I started to hope that it was a dream, so that I could wake up.
I had time to stop and to try to wake myself up hoping that this was a dream, so I decided to try to lay on the ground/grass and go to sleep, and for some reason I thought that would wake me up in the real world.
I was still too scared so I could not get comfortable enough to go to sleep in the dream, so I kept trying to relax myself, and I kept telling myself to wake up out-loud and in my mind.
I decided to also think/imagine myself waking up, hoping that visualizing this would increase my chances of waking up, and before the two Grey aliens came around the corner of the house I woke up; and so I successfully woke myself up from the dream from within the dream on purpose.
Since that day I have used this technique/ability to wake myself up from dreams when I want to, and using this ability/technique got easier and easier to do each time that I used it.
After having used the wake myself up from a dream technique/ability maybe three or more times after that it became easier to where all I had to do was to close my eyes and tell myself out-loud and in my mind that I wanted to wake up, and I would wake up.
Later I started to be able to wake myself up by just blinking my eyes while just thinking that I wanted to wake up.
Now I automatically wake myself up on accident usually in the rare dream/dreams that I get too scared in or I just wake myself up with a thought/feeling of wanting to wake up.
This technique/ability usually works for lucid and non-lucid dreams, but there has been a few rare dreams where I possibly could not wake up.
