Hello and welcome to DV. As you can see I'm fairly new, but I have had lucid dreams after joining this website. Just lying there, most likely won't make you lucid or in SP. For one you need to be fully relaxed and you must not let your mind wander! There are many techniques you might want to check out like WILD. There are guides and tuts to look at and give me PM if you want any help in anything!

One technique I use that's really basic is if you feel like your mind is about to wander concentrate on your breathing. Nothing else. Just the inhale and the exhale. It helps my brain from going places and it also helps me^ relax. I'm no expert but here there are plenty!

You also want to make reality checks during the day to see if you are dreaming or not. It may seem silly, but once you are dreaming you'll hopefully do a reality check and become lucid.

Keeping a dream journal has helped me^ the most. Keep recording those dreams, and your dreams will become more and more real and vivid.
