I've had something similar since at least my teens. At night if I look closely at streetlights, I see what looks to me like a magnetic field around streetlights. I don't think that's what I'm actually seeing, but that's what it looks like.
As mentioned in another message, you may have astigmatism. I get triangular spikes off of relatively point-sources at a consistent angle of about 10 degrees clockwise from vertical from my astigmatism. Your angle will vary, of course.
