Hi Miriam;
I believe what you say regarding getting the energy sucked out of you. It is not so weird as many people have experienced this.
In Level 2 Master Lin gives a Hand Mudra that helps prevent others from stealing your energy, it has been invaluable to me on many occasions.
In my earlier days of training my 1st teacher and I talked about this and he recommended doing daily breathing exercises which eventually made me strong enough that this was no longer a problem for me most of the time.
In SFQ, my opinion is that it is much more effective at raising your energy level much faster and when you hit that right level, these things will cease to be a bother to you.
As in the shark story above, you will become a big shark and pretty much get to go where you want. They give you the space and no one can take your energy. (Unless you're feeling foolish enough to take on a larger shark who may be gracious enough to teach you otherwise)
At some point in your developement (when you are strong enough) you may want to go back and visit your Vampire friends to forgive them and maybe say thanks for the motivation.
Have a Happy Day
Jeff
