We sleep with a baby monitor that lets us listen to sounds coming from Evelyne's crib. It's merely a one-way radio that's either on or off, with one dedicated band. Normally Evelyne sleeps pretty heavily, so we're lucky if we hear a few squeeks each night. Last night I awoke to hear a low, abstract noise, sounding like a distorted voice, then Evelyne responding with a squeek. In my half-awake state, my reptile brain first assumed that an intruder was in the house, in Evelyne's room. Then my human brain decided that this didn't make sense. If a person was going to break into my house, they wouldn't be talking to the baby.
Then I heard the sound again, and Evelyne squeeked again. Now more awake, I realized that the first sound coming from the radio was something like the sound of a call being intercepted by a cordless phone (a crossed signal). It was still very ominous, (especially from Evelyne's point of view), but I was certain it wasn't an intruder in my house. As I drifted back to sleep, I though of another explanation: aliens. Aliens were trying to abduct my daughter. Or they had already abducted her, and they were bringing her home via transporter beam. Either way, it was aliens.
Evelyne seems to be OK, so I think it's nothing to worry about. But if those aliens ever sneak back into my house, they're in BIG trouble.
