I'm going to answer your question as two questions.
Fristly as to what I'd do if I encounter aliens. I'd simply do as I did before, lie on the table in a state of semi consciousness staring at the blurry pink and green images sticking all sorts of sharp pointy objects in me and as before hope they leave me back in bed just in time for breakfast. Although this time I'd prefer not to wake to find that I've got eight toes on each of my 3 feet.
Secondly as to what I'd do on getting out of bed and meeting an alien. I'd blink and blink again, strain forward trying to focus, blink again and rub the sleep from my eyes. Then I'd breath deeply and simply say, "Honey, I don't think that look will go down well at work today".
Then I'd go downstairs and have breakfast with my wife as usual!!!!!
