Here I will post my observations about Limitless specifically. I was waiting for this kind of sub for a long time.
First of all, Limitless (both standard and X) induced a very intense dreams. Second thing I felt that Limitless is somehow integrates the results of Emperor and S&S in me. This is very hard to explain but…its like Limitless says to me: here what are the overall results of previous subs…and this explanation is in form of intuition or retrocognition just like «here are right answers to your questions». Very interesting phenomena.
