I am a third generation medium, what you are hearing are are spirits,at night spirits find it easier to communicate,not for a creepy reason, that's just films!
It's because they are a energy and appliances ,lighting , general daytime use of these items,are draining,most of them are not used at night as it's easier for them, groups talking is aiding and assisting, it will be family linked and is a discussion of what to do ,and to help,you often get this in houses if you are a visitor to it,it's a gathering of curious spirits being nosy!
Don't be afraid ,in 30 plus years of this ,and my mother's ,and grandmothers lives as a medium ,bad stuff is very,very rare and only of you're not careful,
Never ,ever be tempted to do a Ouija board, it's not something to dabble in !it's like opening your front door to see who wanders in!
Spirits come with love and caring,and only really when you need it
And only in a way thats comforting for you,they love you they don't want to scare you!
If your needing to know they are there ,ask! Say it out loud,ask if you need help,it will come.
Life does go on ,as does love,I have seen spirits many times ,and they have been trying to help, they don't hang around watching you!! It's like phoning a friend ,you want to have a chat or some advice,or connect with someone you miss.
Think of it like that,
And blessed be to all.
