Hey jzinser,

This is actually a fairly common method called Dream Exit Induced Lucid Dream (DEILD). It's generally defined as waking up, remaining completely still, and then drifting back into another dream (possibly even the same dream scene) while remaining lucid. It's a good way to chain lucid dreams - that is, to string multiple lucid dreams together for an extended period of time.
