Because you are not asleep.

Lightning is very bright. You eyelids block a lot of light, but not all of it. If you close your eyes on a bright day outdoors, you will still see "red" through your eyelids; you're just seeing the tissues that make up the lids themselves, as well as the blood, because the light is so bright. Similarly, you will see some light during lightning even if you close your eyes, becuase there is so MUCH light.

You don't "close" your eyes. Your eyelids are more like filters than they are lens covers. Their function is to keep the eyes clean and moist, more so than to provide darkness.
If you have your eyes closed in a dark room, and someone turns on the lights or takes a flash picture, you can tell. It doesn't have to be as bright as lightning.

You still see lightning because the layer of skin of your eyelids is thin enough that the light energy can still pass through. Another example is if you were to hold a light on one side of your fingers/hand. they will turn bright red because the light travels through, but if you try through your whole arm then it wont work because there is too much mass.

Your eyelids are not opaque, that is, they let quite a bit (2%?) of light through. Lightening is so bright it passes through the eyelid easily. But you can see the sun through closed eyes, too, can't you?

Our eye lids are translucent. So, bright light does come through with reduced intensity.
