To be honest theerapun, I'm as amateur of a Paraliminal Tape user as anyone on the board I've only really been using the tapes for a little under two months and I'm having my share of frustrations in getting any results out of them. Out of the three tapes I've used to date, only dream recall has resulted. Now a run down: -I started with Self Esteem Supercharger (no noticeable result), than went on to Dream Play (remembered one dream out of around two weeks of using the tape) and than started using Memory Supercharger. I listened to the tape once a day, always at night and an hour before going to bed. Now whether dream recall was the result of combining Dream Play and Memory Supercharger or listening to the tape an hour before I went to sleep...I don't know. It just happened the first night after I listened to the tape. And from there on, I remembered more dreams with greater clarity each consecutive night I used the tape. Now I remember at least one dream a night with clarity (even without the tape)! But as for your other questions, I'll attempt to answer them now:
1.)Answered above
2.)I have absolutely no idea of any lucid dreaming techniques...I don't even know what Mild Wild reality check is...perhaps you can enlighten me
3.) I find this whole frequency thing interesting but have no clue about...would you mind sharing some knowledge and providing some insight? Thanks.
4.)I listen to the tape, spend an hour getting ready for school and than go to bed. I wake up in the morning remembering dreams that I was in direct interaction with. It's a neat feeling.

But as I said in my earlier post, I purchased memory supercharger to improve my recall and retention of information and facts from school and reading. Dream recollection has only been a fluky development that just happened. Once again, good luck and I hope you have more luck with paraliminals than I've been having.
