Physical Manifestations, Utilizing Will Options

Lets say this is a given: someone I know is able to manifest small, organic, of-this-world, creatures when things get dire, or out of hand, or even excited (sometimes during hard concentration).

This person is interested in being able to control this manifestation through will, they have tried a sigil with no luck, and have memorized the creature's name in Latin, reciting that seems to narrow down the species when it happens but still has trouble doing it when they want it to. I don't expect a bunch of people to give useful information, or even believe me but my friend insisted I asked through here because I don't know any more advice I can give them. This person wants me to ask this question on my computer to keep things anonymous.

Dire emotion can certainly be a part of the creative process but not a dependent one...ie I paint some rather inspired artwork when motivated by emotion but my artistic creativity doesn't always involve emotion. Do you see?

An anecdotal tale is in order. I know a rather lovely woman friend who is multi-gifted on a number of levels. Currently she packs a 9mm handgun and runs down illegal aliens and dope smugglers in Miami. She has learned that she also has some fairly strong psionic abilities that tend to flow from a very natural aptitude in shamanism. She never claims to be a shaman as she is a police officer and not tending to the less material needs of her community (OK, we can have that discussion elsewhere...?) When she finds the need to center herself in order to pick up on various 'vibes' the local area becomes infested with flying insects...usually bees or wasps. It is freaky. Now I'm not saying that she is actively manifesting these guys or merely calling them...I leave that explanation to those who wish to discuss it. At her home you will always find either honey bees or dragonflies, at any time of the year! Things that make you go hmmmmm.

By what you've relayed in your post, I'd say that you/they have got a good handle on some of the trigger mechanism I alluded to in my post. Again...standard operating procedure...write this stuff down! Time of day, nature of manifestation, feelings/emotions felt, recent food or sleep cycles, thoughts, overall health, etc. As close to scientific notation that you care to observe as soon as you have the opportunity to do so! This will help you to see patterns that you might overlook upon reminicsing(sp?) the occurence.
Good journey!
