I never did acid so why do I have crazy dreams?

My daughter woke me up at 5:30 AM. She wanted to watch the Little Mermaid.  She kept asking for Ariel.  So I put the movie on, went pee, smoked a cigarette, and layed back down.  The baby was watching the movie, clapping her little hands.  I drifted off back to sleep (so did she).  I had the weirdest fucking dream.  In real life, I am on medication.  I'm on Paxil and Buspar for panic attacks and I'm on the pill.  I'm also on antibiotics right now for an ear infection.  I haven't felt the need to take the panic medication the past few days and I always forget to take the pill.  In my dream, my doctor was coming to my house and I had to take all the medication I missed.  For some reason, my brother had an OxyContin pill and I stole it from him (I had an addiction a couple years ago).  I was in my bedroom, about to crush up the Oxy to snort it, and I was about to swallow all of my back doses that I had missed when I decided to look out of my bedroom window.  On the wires right outside of my window, were about 10 enormous horse heads.  Don't ask me.  They were moving along the wire.  I looked down into the street and there was a horse and carriage coming up.  The horse looked up, saw the horse heads, and freaked out.  I leaned against my bedroom window and it fell out; I fell with it.  The window landed way before I did, right in front of the freaked-out horse.  I can't remember if I landed or if I was about to land when I woke up. What the fuck is that dream supposed to mean?!?!
