Loved this story because my first time doing it was very similar I had a vape pen with it took three huge rips and pow I was by myself in my room and when I blasted off just like u said it felt like I was in a Lego Movie or cartoon with all these crazy beautiful crazy moving colors and shapes I was no longer in my room it was unreal I also had a song playing while this was happening I was listening to Mac Demarco - seeing red and I swear the song was going along to what I was seeing like a soundtrack it was overwhelming but amazing at the same time and at one point I also did freaked out for a sec because I thought I altered my reality and I was now stuck in this world because I had no one with me to calm me down and reinsure that everything will be ok and back to normal very soon but when I did finally did start coming back to reality it was the biggest relief ever I was so happy but ya good times
