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

  You should have your eyes checked. Halos around bright light sources may be caused by cataracts. Cataracts generally affect the elderly, but young people may also have it due to genetic factors or medication (such as corticosteroids).

  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.
