It's up to you to decide which Lucid Dreams count if you want to keep track on your progress. It's just like KingYoshi said. If you have a goal set up, and focus on achieving that goal, you'll have an easier time next time you get Lucid. It can help you spark your consciousness back to life 100% and you'll be able to look around and do whatever you feel like

If you have any questions, don't hesitate to ask here or in a PM. Good luck!
