Cause it's relaxing.
you need to keep an alert, upright posture to try and prevent that from happening. And preferably not be dead tired.
You did it too well :)
meditation is relaxing too see things. Get the sleep you need a few months in a row as you keep doing the meditation:)
Because it works ! <br />
Why doesn't anyone tell each other that it's OK !
Because you body 'knows' when it needs sleep and when you are meditating, it is safe to do so.
It shows your mind into lots of chattering.You can not relax due to chattering of your mind. While you drop your mind means stop chattering and get alert. Mind easily going into relaxing stage and you will go to sleeping motion. So relaxation or sleep is necessary for you and you are not received due to your mind is not alert. Since sleeping is too important for you do not stop meditation. Once it is cleaned you will able to meditate.
If your tired or meditating in a comfortable position; such as laying down then that may be why.
lol, I have the same issue. I just can't make out if the relaxation comes from the mediation or the light state of mind under the influence of drowsiness.
Because it is really relaxing and you are at peace with yourself.
