The easiest method is repeating "I will lucid dream" over and over again in your head while you lay down I herd it's about 30 40% chance of working which is pretty good since you aren't doing that much
this happened to me last night, I was being chased by some random monster thing and then I realized this might be lucid so I teleported the creature to my domain and use hollow purple on him eradicating it from the face of the earth
If you’re lucid dreaming, you could technically make the monster Mike Wazowski scream when you stick it with a massive sword that spawned in your hand, then take the Petercopter to McDonald’s. Lucid dreaming sounds interesting to say the least.
