Not sure what to make of this

So I've been attempting to astral project for quite a while, but have yet to succeed. I've reached the vibration stage but woke myself up because of some negativity.
    A friend suggested I use tektite to aid my attempts, so I went out and purchased a piece. Apparently the stone can vastly enhance your projections and allow cosmic travel when placed upon the third eye, so I did so accordingly.
  My cousin was staying over with his girlfriend and I had already turned in for the night. With the tekite on my forehead, I started the usual procedures. I ended up knocking out since I attempted projecting without sleeping first, but was woken up by my cousin around 3 am.
    Apparently his girlfriend and him had heard knocking downstairs at the front door. It had stopped once he woke me up and upon surveying the yard, not a soul was in the area. For those of you who have seen the Insidious movies, the twist (for those who've seen it) in Insidious 2 was exactly what came to mind after I had registered all the events and their relative significance.
    What are your thoughts on this?
