so I don't know if anyone else is having this problem but i figured might as well ask. I'm a decently experienced Lucid Dreamer using MILD but I decided to try FILD last night. I woke up at 4 a.m. and started the technique. It felt a lot like the final stage of WILD but for some reason my heart started beating insanely fast like it was gonna beat out of my chest and it felt like I was blinking with my eyes closed like they were "flickering" (best word I can use to describe it) and they were flickering/blinking insanely fast. I don't know exactly what the problem is maybe I just need to practice it and get used to it more. Any thoughts?
