Aidan,
I know you wrote this a while ago but I just stumbled on it.
The answer directly from my spirit guides and yours is a huge, warm YES!
Definitely ask them to connect in dreams and meditations, they would LOVE to come into your life in a more definite way! There is no spirit guide that is not a being in light, so if you meet a spirit guide that isn't surrounded by light, its your own imagination and negative thinking thats affecting it. My spirit guide Jia assures me (and she NEVER lies!) that a spirit guide cannot be anything but love.
