Is there any relationship between Insomnia/Shift Work/Sleep Deprivation and Lucid Dreaming, or does lack of sleep/change of sleeping times bear no relationship to Lucid experiences whatsoever? The reason I ask is that my most lucid experience followed 4 days during which I changed from day shift working to night shift working and I only had approx 9 hours sleep in total due to insomnia, work commitments, childcare issues and appointments that I could not get out of. I have had lucid experiences before but not to the level I had on this recent occasion.
