Many things: Vasospasm in the posterior circulation of the brain can do this. We see this with basilar migraine, HV syndrome, concussion, low blood pressure, hypoglycemia, etc. If it happens more than once let your doctor know.

Blood flow!: Decreased blood flow to the brain can cuase these symptoms. Usually exacerbated when changing from lying or sitting position to standing. You may have a problem with your vertebral basilar arterial system. You need to see an ophthalmolgist or your pcp.

Many things: Problems like these can only be correctly handled by your doctor in person. He/she needs to listen to you, perform an examination and possibly run labs or other tests. That's the only way he/she can find out what's going on and what to do about it.
