I for one love taking naps after lunch, like 1-2 hour nap. It gets me all rest up, the food is all taken care off and it seems to help remembering dreams down to every detail, and they could be long or short, but their normal as at night, if you wish to become lucid you will have to do it the same as always, either wild it or just know your dreaming. i just woke up from one like two hours ago
