A Flash? Options

Hey guys (IMG:style_emoticons/default/smile.gif) It's been a while since i've been on here and it's good to be back (IMG:style_emoticons/default/smile.gif) Well I should have posted this earlier & i'm not sure if this goes here but anyways:

I was sitting at my computer just answering emails etc and all of a sudden I heard a popping noise like popcorn popping but only once. It could have been from people downstairs making noise so I just dismissed it. A few seconds later I saw a flash behind me, like a camera flash. I saw it because it was about half as wide as my room in width but in length it was thin. Anyway well I didn't bother me to much so I just let it be. (I've gotten used to paranormal things alot more now) A few minutes later I was shaking like I was exausted and kinda dizzy. It was like the energy got zapped outta me. I left the room because whatever that was it was draining my energy. So i came back a while later and it was gone. Anybody ever heard of anything like this? Also there was nobody in the room besides me and this was at night, thats why I saw it clearly.

Thank you ^-^

Given that it wasn't a ball of electricty discharged from a socket or burnt out light bulb (both can produce popping noises), its sounds like it was some kind of astral parasite. As you get more and more advanced in magick you'll realize that lesser entities are drawn to you and they'll try to feed off your heightened level of energy. I'd cleanse your property and make wards to protect yourself and if those don't work then do a banishing ritual.
