Which techniques have you tried and why you didn't like them?

2 main techniques are WILD and DILD. They can both be aimed for together. WILD at nap time, or middle of the night with WBTB. DILDs when going to sleep normally.

They both require daytime practice. But the good news is, that practicing for DILDs helps with both DILDs and WILDs, and vice versa.

Also, read up on DEILDs in case you find yourself in right conditions to do a DEILD.

Happy dreams
