[Objective]

Natural lucid dreamer here. Can recommend flying and building your own landscapes/cities Inception-style. Can recommend lucid dream sex too, it's top 3 sexual experiences in my life. Not even joking, if you haven't had one you're missing out.

Edit: What Veritas is touching about speaking/having conversations and remembering them is also really great for having analytical conversations with yourself in ways you'd need drugs or heavy meditation to reach. I've done it in a couple of lucid dreams and it's given me insight I otherwise wouldn't get. This happened before my experimentation or regular use of weed on occasion and other substances.

Also important to note: Lucid dreaming can be physical draining (not always), expect a decline in energy when you wake up. However, if you struggle with nightmares and you can identify what's real and what isn't and can't wake yourself up you can direct your dream into more favorable experience and get control of the demons that haunt you in your dreams.
