When spirit comes through in minds eye

[tabane27]

My Nan passed few years back and she came through last night in my minds eye. This is usually how I see spirit. When she came through there was no message or nothing. As she stood there looking at me I realised something and never thought about it before until last night. With her was my guide but they were not standing side by side. Behind my nan was black void.
Since she’s passed away she’s always come through in the same way like she’s just appeared from the void.
When I have seen other spirits in my minds eye there is always a background, always. But with her not.
I’m now thinking has she not moved on after these years gone by. If so why not. Or is there another reason. I don’t understand. Can anyone help me with this one
