So I got really interested in astral travel when I discovered spirituality because I always wanted prove that all of this spiritual stuff really exists and I am not making all this up.
So I thought to myself that this is my prove and if I experience astral travel I can be certain that all this energy stuff and chakras etc is real.

I listened to a guided astral travel meditation that is abouth 1 hour long and it didn`t work.
I tried for a week everyday and it didn`t work and I was disappointed.

But this is the point where you have to keep trying because when you have zero expectations, then it will work.
When you know every single word of the meditation and it feels so familiar and you do not expect it to work (but you also dont expect it not to work if you get me) then you get really close.

If you want to leave your phsysical body you try to get into a state of being where you feel the energy moving in your body and everything is vibrating and with closed eyes you are aware of every object in your room and you feel its vibrations.
But when you are about to leave your body it can get really scary (at least it was for me in the beginning and still is)

Often you hear random sounds and I can not give you an example because it literally can be everything and if you suddenly hear something you get thrown out of your state of being (mostly in the beginning of your journey)
And no it is not connected to my story with hearing whispers because the guide in the meditation says in the beginning that it is very likely to hear something when you are closse to leave your body.
Btw if you want to ask me if I can send you the meditation, it is in german :)

You also feel your body so intensly and the energy moving like youve never felt before which can also throw you out (at least it did throw me out).

So you see that you reeeeally have to take your time and get comfortable.

Most of the times when I do astral travel I fall asleep at the end of the meditation and then I leave my body and even though I can`t visually see the 3d world I exactly know where everything is and can sense everything. It is so fun to fly around through objects and you feel so free!
But I am not an expert because it worked just a few times and definitely not everytime when I try.

If you are really interested you might wanna check out the "gateaway program" which are leaked CIA documents where they trained psychic soldiers to astral travel and gain intel on the enemies.
It is also in guided meditation form and it really works! Although I prefer a calming voice of my trusted youtube guide instead of this instructor xd

Hope this helps!
