I have been meditating for a few days in order to reach the astral plain. My sessions are deep, i lose feeling, my breathing shortens, and when i reach the vibrational stage i feel sick, and come out of it after a couple minutes. I am hoping to pull through eventually, but my main concern has been the long term side effects. When i wake up, i have badly blured vision which last for a few minutes, but my long ranged visions has stayed that way since my first session. Is this normal? And will my vision improve? I could also use advice on how to stay calm through the vibe stage.
