Ooh, I tried this for a couple of days a few years back and it didn't work. Normally lucid dreams happen to me when I'm already mid-REM and suddenly realize none of this is real.I had lucid dreams in the past, but not regularly. It helped doing reality checks: I asked myself a few times over the day: "Do I dream now or am I awake?". After a while I also started asking this question during dream states. But it also happened that I just woke up instead of getting lucid in these moments.
