NO! what you describe is not Astral Projection.. It is a similar but somewhat different occurance - somewhat wrongly labled - but mostly called "Remote Viewing." If Astral Projection then your physical body can't do any movements or actions; besides it is a little more preparation to actually move your Astral being out and around.
The terminology is somewhat wrong; but for lackof better 'name' I will remain. Maybe it should rather be Remote Sensing or Remote Awareness.
This phenomena is part of our human nature but has been surpressed for ages. Anybody can learn it; you have it natural. You seems to be young; I will recomend you treasure the blessing you have and never to loose it. Sometimes it might be a burden but mostly it will be a blessing.
When you devellop this you will find it more and more usefull in your future life - and it can save so many lives too; especially when it comes to you, your friends and family. I am writing a new article about exactly this thing called Remote Viewing; give me another day or so to get it up!
You might also notice the 'awareness' is stonger when he is far away than when he is close near you i.e. next room.
Enjoy, be happy and use your natural blessing!
