I haven't experienced that and haven't seen anyone post of that, but bright sunlight seems to be a common trigger for those in cycle so it doesn't suprise me that something like that could trigger an attack.

There's a distinct light pattern has triggered individual hits for me even when  out of cycle, so no reason the laser pens aren't doing something similar for you.

This also gives credence to calls for selective euthenasia.

Different people tend to have different triggers, but for the most part all that information is anecdotal. Alcohol is probably the most recognized trigger for cluster, but there are other common threads like heat, light, etc that migraine sufferers also complain about that cluster sufferers report.

I personally feel open to attacks when I get hungry and when I'm around cigarette smoke.
