Things that have increased lucid dreams:
Intention intention intention! If I say to myself that I'm going to become aware that I'm dreaming in waking life and before bed, it almost always happens. Throughout the day, having reminders to check in and let the thought 'am I dreaming?' play in my mind.

If for whatever reason a dream goes wrong and I can't end it, I've gotten into the habit over time of jumping off a cliff to escape into another dream or wake up. As soon as I turn around, a cliff is always there waiting for me. Once this becomes routine it's not as scary and can actually be a lot of fun.

Also just a little thing I do with dream journaling. If I'm too tired or busy I'll quickly babble a few things into the voice record app on my phone. Then later will jot them down in my journal.
