Good post Rommie.

( for the new nickname)
I have been so scattered that would have taken me a couple of days.
I do want to reitterate the "DON'T BE AFRAID". Fear is like a lure for those who want nothing more than to pray on others and by allowing that fear to flourish you do nothing more than tie you own hands. This not only goes for the "psychic attacks" but for physical ones as well. No one can feed off you except that you, in some fashion, allow it.
A couple of other things to note... In the "tree" visualization, you can draw and shed limitless amounts of energy. This is a good exercise to just get really familiar with. You don't have to be standing still to do this either. I find it quite fun to "turn into a walking tree", it tends to throw some predators off. And leaves them open to becoming prey (so that they can see how it feels of course).
You can also use lavender or patchouli as a protective scent. And for stones and cyrstals anything black will help with warding and protection. Snowflake obsidian, apache tears, jet, black chalcedoney as well. If you are male I would stay away from onyx. It is not a friendly stone for men but it works great with women.
Be careful with "aromouring or shielding" as well. You need to be able to let some energies in while keeping others out. In this case it is probably better to rely on herbal and stone help untill you can find the appropriate type of shielding visualization.
I know we also talked about keeping it light but this just seems appropriate here... It never hurts, if you think you are being attacked, to attack back. This falls under self deffense anad no matter what "path" you follow it is acceptable. Take some time to develop that "bite" and it will give any that might think they can pray on you a second thought after the fact. Of course if you walk away with a bigger chunk....
Any time you find yourself attacked during "dream time", it is good to know that you can call on your guides and allies for help, as well as your totem. Don't think you have any of those? You do, all you have to do is look around. Sometimes those who are close to you in waking time can come to your aid in dream time as well. Just remember that you are never alone, and you will be able to handle anything in dream time. Also the same rules for harm apply here. No one and No thing has any power over unless you allow it. I keep saying this but it is true. I am speaking from experience not just from some book or philosophy.
Keep your guard up and your mind open, and most of all...
Be at peace.
