As of late i have been (when not thinking about the subject of dreams) i have a flash of alertness i like to call it and pretend i have just realised i am dreaming. I do this numerous times throughout the day (sometimes) and when i am doing it consistently it brings great results, like the other day i done it several times and that night i had 4 lucid dreams (2 lasted seconds) and in three of them i become lucid through a flash of alertness (suddenly realised i was dreaming).

I'm not sure if this is a technique but i thought i would post it and see what you think.
