First Day Back to Work; Dream? or Nightmare???

I couldn't sleep last night, knowing today was my first official day back to work even though I opened my class last week. Friday when I went in I stepped on a rattlesnake, I didn't get bit, I got lucky, but still it happened. Last night I dreamed I walked up to my portable and the snake was there waiting for me, blaming me for it's death. I think our AP killed it, although I thought it might have been relocated. Anyway it was waiting for me and said the only way I was getting in that classroom was through it and no matter how hard I tried to convince it to let me in it wouldn't. We had a stand off, and it wasn't going to give but I didn't want to get bitten, and I knew it was going to bite me. I was thinking that even if my son and I were arguing I still didn't want him to have to worry about me dying right before he went to Afghanistan. It drove me nuts all day and everywhere I went around the school I was looking for that snake~!
