Hey, I´ve been thinking this for a long time. I once accidentally woke up in the middle of the night, after about four hours of sleep behing. And I could remember entirely normal dreams, that could have potentially turned lucid. If I wouldn´t have woken up, I wouldn´t have remembered those dreams in the morning.

So, the problem is: When you get lucid, the chance is something like 40% that you´re in your last rem cycle before waking. So about 60% chance you wont remember this in the morning. So maybe we have had tons of lucid dreams that we just don´t have any idea about. It feels like we have lucids just in the morning, but is it just because we remember those lucids? That´s a real problem. I would be really glad if someone would link a study that says we actually have our lucids in the morning.
