How close to a lucid dream was I?

I have very rare episodes of sleep paralysis and knew little about it. I swore to god I thought I was being attacked by demons some of the episodes I had but I hear that is a very common affect from it. So I got on the internet and found out from sleep paralysis and I can enter a lucid dream. I thought to myself well that will be forever from now because how rare I experience that. So I found the meditation process where you slip into your dream awake. I carefully read the meditation process and tried it out. I feel like I got pretty close to the point I enter the dream but I got really relaxed last night and thought only about my dream I was going to have and after minutes of laying down with my eyes closed I saw lights dancing around behind my eyelids as what is supposed to happen. I saw a blue windmill light moving around clockwise, then I saw red blinking lights and gray clouds shrinking from a large m and into a small m moving up and disappearing and then the large m reappearing. I thought it was pretty cool. Then I saw like a gray cloud that shrank and enlarged and my mind felt like I was flying through a tunnel as if the cloud turned into a tunnel as I was going into the tunnel I felt more and more unattached with my body and finally I saw a black room that felt 3d..I'm not sure how to explain it but I didn't get to find out if I was nearing the dream scape. Something snapped me out of it and I opened my eyes and it got ruined. Also I just didn't feel tired enough last night to fall asleep maybe that's it? What did I do wrong and was I close??? Any tips from those that can do this?
