Heya, when I was younger, (about a month after I'd first got into wicca) me and three friends (one also practised wicca) decided to go on a sleepover. A lot of things happen and we ended up admitting to out other friends that we were wiccans (coming out of the broom closet, you could say XD) The friends took it surprisingly well, and asked if we could try a spell. My other friend and I decided to start with something basic but still effective- so not to freak them out or anything. Eventually, we decided to try out a "vampire" spell. It's more of a power spell, but you do end up with fangs. Here's how it goes:
Blood red, pale skin, moonlight, draw me in. Quench my thirst, coursing veins, let my body feel no pain.
We each repeated this 10 times, once at a time at about one o'clock in the morning. I was to go last.
The thing is, when I chanted mine, things started going wrong. Apparently, all of my friends felt "an electrical charge" run through them when I was chanting. That was weird, but then my, also wiccan, friend started crying out loud because she could "sense something bad" in the room.

I was wondering if it could be a demon I once communicated with and put a lot of trust in when I was younger. (and stupider) I never really got over what feelings that demon left me with when it betrayed me. (VERY long story, I don't really want to talk about it)

Could anyone please explain this? What should I do?
Thanks, peace be with you :)
