I've always had experiences since as far as I can remember. But these two experiences started almost at the same time around junior year high school. My Mother and I move out of my Grandmother's apartment on my seventeenth birthday, shortly after the move, I started seeing sparkles of light. I still remember the first time I ever saw a sparkle. I was laying on my bed and I was on my phone and from the corner of my eye, I saw very bright sparkle of light. I quickly turned my head to investigate the flash of light but it was gone.
Since then I started seeing the lights more often. I only saw them in my house or even at my front door when I'm coming home from school, almost as if it was greeting me. At the time I only saw them in three different colors; white, blue, and purple. I never knew what the colors meant and I still don't know what they mean. As time went on, I saw the lights more often and even saw them at school. I was so scared of the lights. They appeared whenever I was relaxed or sometimes when I'm just sitting down playing my guitar. I was beginning to think I was going insane.
One night I was trying to sleep and I heard my first voice. It was a whisper that I heard not physically, but mentally. It said "Call me crazy". I immediately opened my eyes, in pure shock. I texted my best friend and I told him all about it. I just wanted to vent, I knew that he couldn't help me. I eventually went back to sleep. After that I started hearing voices but only in the night time when I am trying to fall asleep. The voices never told me anything important, as a matter of fact, the majority of the time the voices aren't even talking to me. It was more like I was hearing conversations between other voices. But when a voice IS talking to me, I'll hear it loud and clear, almost like it was spoken at my ear.
Fast forward to a few years, I see the lights every day, I see them in many different colors, and I also see them almost everywhere I go. I read that the lights could be either angels or just very good spirits. I still have no idea what exactly the lights are and what the different colors even mean, as you can't believe everything the internet tells you. I hear the voices more clearly, mostly when i'm trying to fall asleep but I also heard voices telling me important information during the day. One time I was doing a meditation exercise and as I was meditating, I completely forgot how long the instructions told me to do it. I asked myself in my head, "Was it five minutes? Or was it twenty minutes?" immediately after I heard a voice tell me "It was five minutes". Later on I look back at the instructions to confirm and it said five minutes.
Another time, which I thought was a very funny experience when I think about it now, was when I was at work. I work at a burger place and I was in the middle of making a burger and I heard a random voice tell me "COUGAR!". I look around, and I see my manager who is a very old lady standing right next to me. She then tried to start a conversation with me but I was so shocked, disgusted, and even nervous to keep on with the conversation. I just said back to her "yeah yeah yeah" and I walked away. I always joked around to myself that she was sexually attracted to me, giving me back massages randomly, all that crazy stuff, But I never truly believed it. I still would have done fine without knowing that personal secret of her of her sexual fantasies. It's none of my business.
One last thing I would like to mention is that I can sometimes see lights around people, but mostly myself. I have this fun habit of putting on my headphones and just blasting music while i'm in the bathroom. I dance, air guitar, even sing. It is so much fun but because i'm in the bathroom, I have a very good view of myself through the mirror. Sometimes I see a very bright, purplish light coming from a random part of my body. When I look in the mirror long enough, the purplish light will shine and shine very bright. Another time I saw that same purplish light from my body was when I was in my friend's car. I as on my phone and I saw the same light on my fingertips. It was so bright I actually had to look around his car to see if there was anything that could give off the same light. It amazes me how clear I see the lights sometimes and nobody around me sees it.
Sparkles of lights are not the only things I see, but I chose to write specifically about the sparkles and the voices only because I want to see what other people has to say about what they are and what they mean. To me, the sparkles of light are one of the biggest mysteries to me. If they really are angels then why are there different colors? Do the different colors mean anything? And why do I see a purplish light on me? I read something about indigo people but I don't have enough knowledge on the subject to make a decision on whether I am an indigo or not. Therefore I won't go there just yet.
Thank you so much for taking the time to read what I had to say I have more stories to come.
The sparkles are not from an angel. Actually, nothing you describe sounds like angel behavior. Angels don't get into shenanigans of any measure. They are far too busy for that. (There are far more demons than angels, and angels are far more powerful.) Your buddy could be a demon or a fae, which apparently is a thing, and you can think of them as similar to demons in that they wreak havok and some fae, unseelie, for instance, can put the same terrifying mood in the air that one might experience with a hellfire and brimstone type of demon. The more sparkles you see, the more power your buddy has. It is different with different entities.
It can help to sage yourself several times and then your home once if the friendship gets out of control or you decide you have had enough, but you may have to do it periodically. Also, since you mentioned angels, if you are a Christian, prayer can also help. Best wishes.
