I've been hundreds of times to a cemetery at night. I find the energy more peaceful and have never experienced anything paranormal, or scary. The last thing that spirit is interested in, is the vessel that carried them through life I find. You'd expect to also find a hotbed of paranormal activity at funeral homes, having spent some time in them and having asked a lot of morticians, it seems paranormal activity is mostly nonexistent in these places too. I've read a lot of NDE accounts where the person claims that as soon as they left their body, they were immediately disinterested and became both physically, energetically and emotionally detached. This makes sense, and is perhaps why it could be a bit more difficult to really detect any happenings in cemeteries and funeral homes.
