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. Later I found my boyfriend warning me about something.
In this dream, being in college could represent a time of learning and growth in your personal life. The message to go to the 7th floor is a metaphor for reaching a higher level of consciousness or spiritual awareness. The idols of Hindu gods in the rooms suggest that you are exploring different aspects of spirituality, and the act of sleeping in the first room suggests that you are starting your spiritual journey.
The prayers coming from the last room could represent a sense of peace and comfort that you may feel from your spiritual practices. The projection on the wall could symbolize a message or insight that you have received during your spiritual journey.
The appearance of your boyfriend in the dream may represent a warning or caution about something that you need to be mindful of in your waking life. This could be related to your spiritual path or other areas of your life. It is important to reflect on what this warning could mean and take appropriate action to address any concerns.
