DILD, or becoming randomely lucid just by realizing your in dreams, is actually a pretty nice way to go lucid since the dream is already pretty stable. From the moment you become lucid, you should try to anchor yourself by rubbing your hands together, examining things in great detail or doing some exercise. The trick is to keep yourself active inside the dream. If you begin to feel the dream slipping away, rub your hands again, or if you lose vision entirely begin spinning while still rubbing or fall backwards.
FA’s are very common after lucid dreams, and it’s another great opportunity to chain them back together. Congrats, by the way, on remembering to RC’s once you had “woken up.” These are seperate dreams, and you need to anchor yourself just like you would in any other. If you have issues going out the front door, jump out a window or tell yourself that when you leave your room, you’ll be somewhere else.
Other good methods include:
*The magic pill: reach into your pocket, you’ll find a nice, pretty colored pill. When you take it, tell yourself it will make the dream last longer.
*Yell “increase lucidity now,” or “increase vividness now!” Whatever your dream needs, yell for it. And I mean yell, don’t just think it or whisper it.
*Flip a light switch while telling yourself that it will do what you need, like make the dream last longer or change what’s behind your door.
There are a lot more ways to stabalize a dream and make it last longer, so I suggest you read this Prolonging Lucid Dreams article in the FAQ’s and Tutorials section.
