Hey I experienced that for the first time last week too. It started with like my foot feeling like it was being tugged and this noise that sounds like static from a electroninc microphone. I dont think i went as far as you because i did not see my dream forming but i was so excited i woke up and worte it down. I kinda wish I hadnt woken myself though. I hope it happens again so I can experience a full WILD experience.
