I've told this story before here, may as well tell it again.
Ive been meditating for about 20 years and into woo-woo type stuff for pretty much all of my life.
Had many bizarre, weird, paranormal experiences over that time. When I meditate regularly and intensely the experiences are always bigger and more frequent.
This one time for a period of about a month I would wake up, in a dream like state, but i'd be aware I am in a waking dream, meaning I'm laying in bed, eyes closed and 'dreaming' then my mind would move to an alien craft kind of near my house, not directly above, but a little off in the distance, 3 greys would be inside kind of honing in on me mentally/telepathically. I would describe what they were doing as trying to scan me, scan my mind, my 'soul' if you will. I would always push back on them energetically, it was just instinctual and also from my work that I have done and learned. Everytime I did this, they would sort of attempt to scan me again, i'd push back and maybe they would try once more, then they'd just blip out and disappear and I would either wake up, recall and remember everything or just fall back into sleep.

After about 3-4 times of this almost identical experience, I sent a telepathic message that was basically, 'I will let you scan me if I can scan you, but I go first, your the ones coming to me, and when I did this, the one grey that was in the middle and appeared to be the leader, got visibly angry, and they just blipped out again and I never had another experiences ever again. If I had to guess, their protocol is they won't allow that for whatever reason and he was kind of just like 'you are a waste of frigging time dude.'

Thats it.
