How can i meditate to raise my consciousness?

im looking for two types of meditation. one where i can possibly astral project, or just control a dream, and another that will raise my consciousness. im a pagan if that helps. i love nature and i think everything in the universe is connected. the people i live with would think im insane if they saw me meditating, so i was wondering if u guys could give me tips on how to do it at night
