Repost {Trying to get to class}

I dreamed that I was in school and I was to give a presentation. I advised my professor that I needed to go get blood work done and he allowed me to leave the class. However I did not get my blood work. Instead I fell asleep. I didn’t realize I had slept for two hours. It was around 11am. I was worried that My class may Be over. As I’m walking back to the building of where my class is I see that there is construction going on to the building. I’m no longer able to walk through the door to the class as the sidewalk was removed. I noticed dirt was where the sidewalk should be. So I walk to the other side of the building to look for a door to get in. I ran into one of my classmates. I told him that I had to go get blood work done and I hope that I’m able to still give my presentation. And that maybe the professor will let me do it tomorrow. I worked really hard on the presentation and did a good job. I continue to walk to look for the door. I noticed that this side of the building was Shaded more than the other side. There was a bug flying around that looked like a fly. I look at my right hand and The skin of my palm was see through. Like I was able to see the next layer into my hand. The fly was able to get into my palm through a small cut or opening. he was moving around in some time of liquid in my hand. Using my left hand I went inside the opening and grabbed him and released him into the air. Then I continued to look for the other door to the building and woke up. (the dream was in color)
