i had something like this twice while sleeping.. around 3 months ago...i woke up feeling like something was trying to take control of my body... i woke up with this huge energy by myside...looked up in the mirror and was all strange...worst sensation but i kept cool... it was the second time.
the first time i was with a girl i was hanging out, we were sleeping together, she woke like screamingg "get out" i woke up like "its mee its mee igor" and she was so scared... the scared energy arount the room was huge...we start to meditate and i end up sleeping... i woke up like her panicking and screaming like some force was trying into my body (that was one of the most awkwards things ever) but in both time i felt the presence of one girl who used to date me, guess she was obsessed with me...
what happened was my one more experienced friend had already felt the presence and asked us to reach out astrally in meditation (my first time reaching out that far- I've only ever reached out locally before), asking us to tell him what we felt but without telling us first. So all 3 of us indepentantly felt the same presence trying to get inside us. My other friend even felt the whole west coast in anxiety.
What I was getting at with my last question was also covered by Hermes. I thought I'd add that when you astral travel you open a portal to our world. Sometimes things can follow you out of that world in to ours. I had a problem earlier this year with my teenage son who was experimenting with astral travel. He had some strange things that he could only describe as alien beings follow him out. He also went through a very tough time of anxiety and depression after that. I think he accidentally allowed some things in to our world and they were draining him. I had to help him with grounding and basically had him put a stop to his astral travel. So not to scare you but you should definitely be careful and practice shielding and grounding.
If you have a few minutes, you may find some of this info. from my prior post helpful as I believe it relates:
