as promised here is a detailed explanation.
The fact that you can get to a state of consciousness like you mentioned so quickly is terrific. This means that it will probably be less difficult for you to master astral traveling.
When we meditate are goals is to still our mind and balance our energies. There are many methods to do this...finding what works for you is trial and error.
Astral Traveling is taking meditation a step further. When we meditate our brain starts to go into different states of consciousness. Alpha Consciousness can best be described as the time when you are going to sleep when you are not really awake but not quite sleeping either.
You seem to have the ability to go right into "instant alpha" this is something that many people have trouble with and takes them a long time to master.
What you would need to do is to work on your creative visualization skills, To do this you can try (( in a meditative state)) picturing an orange, try seeing it in explicit detail, notice the texture of the skin, its shape, its smell. try picturing it in your hands and feeling the weight of it. Once you have gotten to a point where you can do this without your mind slipping into scattered thoughts then you can start trying to picture other things that have alot more detail such as whole scenes of a painting etc. Eventually you will be able to do this with extreme clarity making out all of the most finite details.
Once you can do this you are ready to start to "travel". There are many plains of existence that are happening simultaneously as the one we live and walk in normally. By invisioning your spirit and feeling it stepping out of your body and slowly raising above you and being able to look down and see your physical shell you are ready to move on to traveling to places. In your mind tell yourself where you want to go and let your spirit fly there on its own. It knows the way.
Yes there are dangers to astral traveling but they are at a minimum. Of course you can encounter certain dangers by going to realms of a more negative nature such as a realm of demons for instance. Should you just want to fly down the stree to walmart to check whats on sale then you shouldnt encounter a problem.
When ever you astral travel you are taking your soul out of its physical living shell that houses it which creates an emptiness therein. In turn this can make you suceptible to an invasion from another spirit be it human or other worldly. This is no a common occurance but it indeed can happen.
There are ways to protect yourself from things like this though. I personally when i begin my astral travel work "See" a a black bubble or curtain come across my entire physical body which "cloaks" me from passing by spirits. I call this the "black shield" It is also a good idea to not only see this black shield as black but also see symbols of power and protection woven into its existence. I also take it a step further by seeing my spirt attached to my physical shell via an "umbilical cord" which ties me to my body so I can make it back should i feel i am losing my way. You can also program yourself with certain words your spirit can use should there be an emergency like "home home home" which snaps your spirit back into place and brings you to waking consciousness. Your physical body is naturally built with mechanisms that sense danger and will likely "bring you back" should it feel threatened.
Astral Traveling while in a consecrated magick circle is not a bad idea either.
I would suggest only traveling "locally" as in this plane of existence in the mean time until you have a few more "flight hours" under your belt
Astral Traveling is a very usefull tool but it is best not to rush these things. Take your time and practice and gradually build up you experience before taking on large endeavours.
There will come a time when you can be at the supermarket waiting to check out and you will just be able to instantly pop on over to the next store you plan on going to and check out the parking spaces
Good Luck to you and Happy Flying
