Procrastinating meditation?

Meditation is a developed skill that does take time I recommend getting a good book on meditation I included a website to find a good book on meditation and they have books on past lives as well as other subjects. As for the noises maybe maybe not sometimes in an open or uncontrolled meditation a hyper sensitivity of the senses or sometimes it is our own random thoughts when the mind starts to relax can occur. I've never heard the term ganja if it is an intoxicant then this helped causing an uncontrolled meditative state that you where not prepared for. I hope this helps and blessed be.
