I have heard a few, so designed my own.
These are really cool sounds and is uplifting.
I have overlayed "You are Dreaming, do a Reality Check now" in it 3 times.
The MP3 goes for 6 mins and the overlays are one near the beginning, one subltle one in the middle and one near the end. Any more and its too much.
I have modified it to loop smoothly, and it is designed to be played maybe once or twice before sleep and then later when you MILD/WILD whatever.
You can play it soft or loud.
Let me know what you think and if it needs fine tuning, or if the link goes dead.
Listen to the whole thing.
Feel free to PM me as well.
