As you can see I'm new to the forum :D
I'm here to know more psi and shields, and perception (especially empathy), and of course interact. I've started having interest in the paranormal last month, and I came upon psi. Generally, I can make psiballs in less than 2 minutes (30 seconds if I have active psi). I can also make a weak shield, generally a bubble shield, and I think it's pretty effective :D. Yesterday, I put up a shield, programmed it to hide me from my teacher's attention, visualized it as a mist. It worked like a charm. He called out about 25 of my classmates (we were 36), and I wasn't called :p. Also, at recess, my friends didn't even notice me I was with them! I won't shrug that off as coincidence, I believe I was shielded.
