As far as lucid dreaming \ dream recall and memory supercharger go, my experiences show that it can be the result of the tape. Though I was listening to Dream Play before Supercharger (with no success might I add), I switched over to memory and right away practically I began recalling my dreams with great clarity. I admit, at first, my sleep was a little disturbed when I realized I was in a dream because it almost felt like I was awake when I wasn't, but now it's no big deal really. I remember all sorts of dreams, depending on how good of sleep I had. But as for remembering facts and things, I myself, after using the tape for somewhere around two weeks, still had no success. And that's why I bought the tape! Dream recall is only an added bonus to a goal I've yet to acheive with the tape. But I suppose that's it. Good luck
