This is lovely. Can I ask how your mum visits you? My dad passed away a few years ago and apart from some very vague dreams about him, I haven't felt anything in terms of him visiting me. I would love a sign or message from him.
I have had visitations from my mum - she got into my bed behind me, but usually she bangs into my aura when she comes up to me to see who my visitor is.
I was told by a psychic that if they love you it feels warm but if they don't it feels freezing cold. So when I feel the warm bump I know she's there.
I went to see a psychic once who described a conversation with a visitor that had been in my house. They hit the nail on the head with everything we'd been talking about.

I can be oblivious though, so a psychic was telling me how my grandad was ranting on the other side at me, as I hadn't been picking up on the signs he'd been sending me.
They've also sabotaged my computer in a job they wanted me to leave.
When my mum was alive she openly told me she prayed every night that I would lose my job.
