Wrong Side of the Bed

What makes us wake up "on the wrong side of the bed"?? There is something that makes us irritable, cranky and just plain out of sorts some mornings. We might get up on the same side of the bed that we always do but... something's off. Perhaps it is the dreaming state we have just woken up out of. I don't know about you, but some nights I have very vivid and memorable dreams. Other nights I can't remember a single thing. But on those nights where I do have vivid dreams... that I remember... I sometimes find that I wake up from an argument. I've been having some dream-interaction with a friend, a partner, a colleague, or whomever... and I wake up in that state of crankiness. Often, I'm like... "thank God it was just a dream"!!! Sometimes I can fall back asleep again... but sometimes it stays with me, shaping my waking moment and clouding my day. I begin to wonder... what does it mean if I'm arguing with people in my dream??? Does it mean I'm holding some grudge against them?? Have something that is left unspoken??? What is the maning of a dream argument?? I don't know, but I wonder sometimes how much goes on in our dreams that we have no conscious recollection of. It's still influencing our subconscious but... we just don't know it... Maybe these are some of the things that shape our day... that we're not even aware of...
