Hi there my friend,

First of all, Congrats on your 2nd LD . Just like what Finlander said, a dream's vividness is quite random. But, you'll still be able increase it's vividness by stabilizing your dream. I suggest you read the official Dream Stabilization and Clarity Tutorial. Just keep up the good work and you'll have more vivid LDs. If you've got questions, feel free to reply back. Hope this helps
