for the past few nights i have been having lucids but it only lasts for a very short while and then i wake up for no reason at all. I don't even get excited or anything, i will just be there walking towards someone or trying to fly and BOOM i wake up. This has happened for the past 4 nights and before that i had been able to stay in my dream for a very long period of time. Its not like i can even feel when i am starting to wake up, one second im in a vivid dream and the next i wake up. Any help please?
