I was at my college and I have got a message to go to the 7th floor, when I went there there were several rooms which had idols of Hindu gods. I slept in the first room and heard prayers from the last room, when I went there, there was one woman praying, when I passed that room I saw a projector from outside projecting something on the wall.

The college could represent a place of learning and growth, while the idols of Hindu gods could represent different aspects of spirituality or religion that you are exploring. The fact that you slept in the first room and heard prayers from the last room could signify a progression towards deeper understanding and connection to spirituality. The projector projecting something on the wall could represent a message or insight being revealed to you. Overall, this dream may suggest that you are in a phase of seeking or exploring spirituality and may be open to new experiences and perspectives.
