In And Out Of Body, Astral and physical intervention? Options

I recently experienced what appeared to be, another person actually entering my body- my physical body- whilst I lay projecting astrally.
Awoken by pain i found actual evidence of a physical contact at the places where i had astrally witnessed a physical scene.
This left me drained for days- physically- since bruising did take some time to heal. The only clue was that the other body seemed to be trying to wake me up and was explaining that I was looking for her. Does anyone have any resources where I can find out about this, I did not conjure the bruising and am totally sane.
I am new to this site but not to magick theorum and would appreciate magick/scientific/ spiritual/personal advice on this matter since all obe/ projection for me have usually been tranquil, accurate and useful- practical times and this has blown me ;so dramatic and painful experience seems to have no logic.

Sorry I am going on a bit - emails will all be replied to and welcomed.

O.O Ive actually done that too. although i was on the other end...and someone received me. its happened twice. Once with a woman who was completely paralyzed, and the other time it was also a woman (i think) who had a friend in the room with her. it was very strange. i had no injuries, but i was very disoriented and panicked for a while. i'm not sure that either of these people were projecting tho. The second time (with the friend in the room) i tried to introduce myself as 'x' and it came out all wrong.

YES i would like to know how this can happen as well...since when these occurred i was completely confused and i was as clueless as the people i entered.

Don't worry I don't think you're crazy. And believe me I've been here awhile now and I have to say there have been FAR more crazy claims than this.

It could possibly be a thought form you created subconsciously, or unintentionally and its trying to sort of say "what do you want me to do now?". I would make sure to record this experience and any additional occurances. Maybe try to make contact with this body through guided meditation and pathworking. It doesn't have to be a thought form either. Some believe that the substance of the soul is much like that of the body and is only temporary in existance. Eventually the essence of one's being ascends the soul, as it did with the body. In some cases this husk of the soul can retain a fraction of its former identity and act like a thought form that was just the product of death. Or it could be just a disembodied spirit unware that it has passed on and its trying to reconnect to life. Maybe it is aware of itself and is trying to possess you. That said I deffinately think you should take safety measures. Lastly it might be one of the many hosts of entities that dwell on alternate levels of reality just trying to contact you the only way it knows how.

Probably nothing to be afraid of, but deffinately use caution, imho.

it took a while but just how i have been told a million times, "listen to the silence" seemed to work a treat and after a connection with Archteypal help, physical advice and a wonderful friend, i am restored hundred fold! thanks people

Floating, feeling light, sense of tranquility will most likely lead to astral projection.
I have experienced it myself and it's very pleasant. You are opening yourself up.
Consider this the first step to your spiritual advancement.
You may feel like you are going in and out of your body. Might even feel a heaviness.
You have to extremely relaxed... I mean really relaxed for this to happen.
Astral projection is when the brain frequency falls between being awake and being sleep.
When we sleep, we dream AND go onto the astral plane where it all happens!
People don't know that but they should.

The mind is the most powerful vehicle, it is the most valuable possession to have.
