No, you are not crazy!!
What you are describing sounds a lot like classical migraine with aura but without headache (it is actually a lot more common than it might seem.) Other causes might be Giant Cell Arteritis or a number of other syndromes, but no matter what it is, there is a very good chance that your doctors will be able to help. By all means, see the doctor, even if it is "just" for your family. Even if you are worried that it could be something really serious (like a brain tumor,) it's still better to have it checked out while something can be done and before you are debilitated by the condition.
Best of luck.

They would happen 1 a day and then go away for a while and now it is about everyday. I am a father of 11 and scared to death of going to the doctor/ Kind of lost.
