Greetings xanadu,
    My condolences regarding the passing of your mother. It's a hard loss, I know.
   If you dream of her and can make yourself enter the dream with a question for her, you can soon be having meaningful conversations with her, but perhaps after mourning has eased.  If you are too tired to rouse yourself, it's worth getting more sleep for this experience.
   Plan your question ahead of time and tell yourself 'I intend to ask my mother----.' It's not hard but it can be exciting so be prepared.
   If you want to be even more prepared, get ahold of Bruce Moen's Afterlife Knowledge Guidebook, and take the whole course.  then you'll be ready for alot of spiritual experiences.
Your grief will ease.
