I experience jet lag quite a bit, but it has never triggered any lucid dreams in me. I can theorize however that it has something to do with disrupting your sleep cycle, especially west to east travel more than 4 time zones. I find that I cannot sleep deeply or for more than a couple of consecutive hours.

It is this shallow sleep that probably accounts for it. How is the quality of your JLILD(Jet Lag Induced Lucid Dream)?

Are they long and detailed or just short and fragmented?
