Dream About Friends Inserting Cannula Patient Rain Cemetery

I was watching two of my friends were inserting a cannula into a patient in my home country. (I am a medical student, sri lankan, currently living in China). They were talking why I don't come often and I was telling that I am getting ready for the lisence exam, that's the only way to pass it in a one go. Then the scene shifted. I was looking for the friends of my mom, in Gampaha hospital where my mom used to work as a pharmacist for years. main drug store of the hospital is familiar to me and we were having a good chat, smiling. My mom's friends were appreciating me like always. Then, I came out of there and it was raining heavily. I walked along passages of wards and came out of the hospital. Since I know the hospital the scenes were very vivid. Suddenly I was walking with my high school friends and university friends in uniforms of my high school. It was raining and I was trying to overpass the uni friends who were talking and walking slowly. Because of umbrellas it was hard, and I couldn't go quickly. Then I saw we have reached the cemetery near my home. After passing the cemetery, it's my home. I wanted to go home quickly and tried to go by a grave. Suddenly i got trapped in to the ground. I can remember when I tried to come out my legs were hit by two three tombs. And I can remember a decaying mummy too. One of my high school friends too was with me. Hashini came and gave hand to her, ganguli. She could finally go a little higher compared to me. Meanwhile budhvin, one of my highschool friends tried to help me but he was so thin to drag me up. Then I was helping ganguli to go up first by pushing her so that both of her and hashini can help me to come out. Then I woke up five minutes before my alarm, 5.25 am.
