A Partner Induced Lucid Dream?

Since my boyfriend is a night owl (I am too, but he is even moreso than me), and often awake while I'm asleep (for a few hours anyway), I had the idea that he could try to signal me when I'm dreaming, so I could have a lucid dream. He has a lighter that has a little blue light on it, so last night I asked him to wait til I'd been sleeping an hour and a half, and check if I seemed to be dreaming (he says he can tell when I am, that he can see my eyes moving under my eyelids), and then flash that blue light at my closed eyes three times, with ten seconds between flashes.

This morning I woke up, however, with no recall of any dreams at all, so I've no idea if it worked and I just don't remember, or it didn't work at all. I'm not sure the penlight is bright enough, to be honest, so we're going to try again tonight and he's going to use a stronger light.

I was just wondering if this had been done before... I was trying to think of a way to help me have lucid dreams (I had lots as a child but only a few as an adult, so far), and I thought hey - he's often awake when I'm sleeping, maybe he could signal me in some way It's still early days obviously, but I'm hoping we can come up with something that works.

Has anyone else tried this?
