I don't think silence is necessary, overcoming ambient sounds would also be a meditation technique of some sort. Personnally I can get lost into a bubble in my head quite easily, I can be sitting on a bus, having music with maximum volume on earphones and still be able to forget I'm in a freaking bus and also that I'm listenning to music.
Greetings while meditating, that happened to me while on psychedelic drug. I saw images as bright as neons from behind my eyelids (disturbing stuff). I was mostly ignoring it and thought it was "funny". At one point it was as if a guy would open my eyelid to pour cofee into my eye. It didn't actually keep me from meditating directly but I stopped to share the events with a friend so let's say it worked flawlessly. These kind of things happened twice when I wanted to go into a very deep meditative state to pierce my veil.
Other than that in my house there seems to be a negative entity which is avoiding me and paying attention solely to my sister.
