D2C cut back on the amount of time you spend listening to brainwave altering programs. Also do not use them every night. What you might be experiencing is dream cycle work that cannot be done because you are loading your brain with material. Sleep learning is great but I never consider it a good idea to do it every night or even the whole night. It lacks balance. Our dream cycle is usually for working through our day to day experiences, strengthen memory on things we learn and releasing. If you've got other stuff going on throughout the sleep cycle because you're impatient to let the change happen with just an hour a days effort I believe it creates an imbalance.

So slow down with all that change stuff, especially at night.
