Well that depends on what you have/have not been doing. I'd say a good way to end a dry spell is to do the opposite of what you usually do!

Like, if you practice tons of RCs, always think about LDing, always try WILDs, etc, then I would say to STOP all that and just forget about everything for a few days. Then hopefully you'll have a spontaneous lucid.

Aaaand if you haven't been trying any techniques at all, then I would go and practice these things vigorously for the next few days/weeks/what have you.



Edit: Oh wow that link is really good.
