The whole chapter three consists of Max's nightmare. First walk towards the table with writing. After you interact with it twice, the text will change into Chloe 4life. You can take a picture of it to your collection. Once you do it, walk towards the door and try to leave the classroom. Jefferson will stop you, you will have to answer his question. Select any option you want and use the exit door again.
The next sequence takes place in the dormitory. First walk towards the crying Kate and listen to what she has to say. Once Kate will jump through the door, use them as well in order to get to the next corridor. Now your objective is to find the correct door. First however, you must walk towards the table on the right side and take the key to room 218. Use the door to room 218 and you will get to another corridor. Once again, you must find the correct room. To do it, you must listen to the voice of the girl that is talking to you. The girl will be Amber, so walk to the map on the right side and find her room. It will be room 224, walk inside in order to get to the next corridor. Now you will become Victoria. Find your (Victoria's) room on the map and walk through the door (room 221). In the final phase you will be Max again. Go to your room. However, before you do it, walk to the table on which the key was lying earlier. Take the picture of the squirrels seen outside the window.
The next sequence will be played backwards. You must get to the room shown on the picture - the bathroom. Before you do it, first take a picture of the skeleton which you will find on the opposite wall. To do it, you must stand in front of it and go back in time.
