Light that isn't there

I'm experiencing strange visual effects on the edge of sleep. Hypnogogic hallucinations or neurological issues?

I am seeing showers and smears of red light (very much like red laser-light scatter) in almost complete darkness; it happens when I am nearly asleep or wake from sleep in a dark room (e.g. after first 90 minutes of sleep). I thus have been lying down for a short time. The effect lasts a few minutes and then goes away.
The first few times it happened I thought I was just seeing red illumination from a neighbor's car backing into the driveway (my room overlooks their driveway). The room is not totally dark; there are 2 windows that are not shaded.
I am not noticing any waking visual disturbances, though I am concerned about this because I have retinopathy of prematurity. Because the red light show only happens when I am nearly asleep, I'm afraid my opthalmologist will think that I'm dreaming.
There is another medical issue: I have a persistent nasal/sinus infection and any swelling could be pushing on my eyes.
