First off what does this mean?
A ghost is just a person without a physical vehicle to operate with in my opinion.

I had a medium once tell me. (especially when I did EVP work) I talked to spirits quite often through devices like recorders etc. The medium to me to help them, (they needed my help and that's why I have so much activity around me.) Why can't they get to the light on their own? What is the light exactly? I got a reply from a ghost once in my room that clearly said "help"

I felt so bad, because how do I help? (Sending them to the light?) I am curious on what this does for their benefit. Can't they do it on their own?

Because if I can talk to the deceased, they are basically next to me only in non physical form. That's the way I see it anyway.

I want to help them... especially when I get better at OBE's. How do I go about this?

Why would they want "the light"
