well, the house wasn't an issue...it kinda felt like he was still there. But I couldn't imagine staying alone. Best to stay with loved ones.
Whew. Tough memory. After my mom died, we sold the house.. no one wanted to live there.. it was all her.
Depressing and nostalgic at the same time.
It depends, if it was a natural death and no negative energy is left, you will never know it. However if it was a violent death or unnatural one, sometimes very negative energy can be left behind and can make that area or even the whole house uncomfortable to stay in.
