too close for comfort
16 years ago
I thought my barriers were stronger, but just now shikagame almost broke through. I can feel him pecking at the back of my mind. while some times he does influence me, I never let him take control. the last time he got out, I ended up losing my best friend. he tries to gain control of me by breaking my nerve through fear and manipulation. I get these flashes of terrifying things, and I see and hear strange things. I've locked him up again now, but for a while I felt like he would break me.
FA+

its not a good thing to allow them to control our bodies but letting them come and go can be a good thing.
but like i said i done know shikagame so the situation could be completely different.
What I can say is that nothing is bad.
for example: shiva. shva brings creation, but first she must destroy what stood in its way.
Pain may come, but as mix just said: you can't be a whole if you deny part of yourself. And if you are not a whole, then you seek to be complete and will never find it.
Do you know what shikagami wants from you? have you asked? have you felt it out?
yup:

looking loosely there's definitely something mystical involved with the name, faerie or demon I'm not sure., though I think they loosely mean the same thing.
