I’m sure everyone has their own unique triggers that will drag them from a deep sleep. I can sleep through New Years Eve fireworks but if one of the kids sniffles or mumbles I’m instantly awake.  The same goes for cat fights and my chihuahua making any sort of noise.  The other night I was really enjoying an action packed dream filled with bad guys and car chases then all of a sudden there was an explosion of noise and I was out of bed in a flash yelling “cat fight” and racing to try to locate where my cat was being beaten up.  Then when I saw the cat window closed it hit me, I no longer have a cat.  She died ten months ago but still my ‘cat fight’ alarm went off in my sleep, so what on earth was that ungodly sound I heard?  Then I heard Luke say “What the hell are you doing?”  So I tried to explain that I heard a noise and I thought it was a cat fight blah blah blah.   It all became clear when he looked at me and said “I blew my nose”.  Not quite a cat fight but I assure you the sound was incredibly similar through the haze of a dream!
