My Mom has told me that she's been having this dream repetitively and isn't sure what it means.
She said that she's just there, kind of standing maybe floating and
to the right there's a bright light and people are telling her things like "It's your time; come with us"
Then to the left, people are telling her things like "It's not your time; come with us"
And she's just standing in the middle and isn't really sure which way to go.

Help, please?

How does your mom feel about the dreams? Do they scare her? Her emotions about them may be a clue to what they are about.

Any way you look at it, it's a dream about indecision and being torn between two paths.
