Thread: I think I began dreaming immediately after going to bed for the night?

I know every lucid technique says not to try it when first going to bed, which I have always agreed with. Most people/studies say you can't possibly have a dream until ~4+ hours after going to sleep. Anyway, last night I went to bed around 10:45pm (earlier than usual for me) after doing some SSILD just to practice it. Around 12:30am I woke up because my roommates were being somewhat loud with their friends, and I remembered several fragments of a dream I had just had. So basically I had a dream less than 2 hours after going to bed. The dream was about a phone app designed to make you become lucid, where you'd enter your info and it would spit out a dream guide for you! I keep dreaming about this same dream guide for the rest of the night and definitely became lucid at one point but my recall for the entire night was very bad. But anyway my question is: was this just a fluke? I had taken B6 last night for the first time right before bed. Could I be one of those people who starts REM prematurely in the night, or do we indeed dream right after going to bed just not very vividly? I'd love to hear y'alls thoughts on this
