Dream About Medical School Incident Uncovering Mystery

this was more of a third person view dream. People were in school and all to be trained to be medical professionals. 2 of the students fell from a glass stair and cut their head with excessive blood coming out. They were both unconscious. They then were sent to a hospital and later on investigation has begun. We were told one of the student was suicidal and tried to jump into the pool and suffocating herself to death. But when police went to the pool they were told it never has any water in it. One of the police/doctor saw that there were something that’s under the mud suddenly their facial expressions changed. When the chief of surgen came with an excavator it was obvious that the doctor that found something under the mud was trying to hide and lie to everyone by not telling the exact location. Later on a patient with dementia stood up and said “I saw a finger and a nail underneath the mud”. This shocked everyone. The patient’s son then apologized to everyone. Not sure if they had dug the finger out. I WOKE UP.
