I believe that if you allow things to carry on, it will answer many of the questions that these experiences are leaving you with. You will always be safe as long as you take time to ground yourself and remind yourself that you are protected by your spirit guides and higher self. Personally, I do this by closing my eyes, breathing deep and before I know it, I can see a white light surrounding my entire body and that's when my body feels okay to sleep or meditate (if meditating).

The glass breaking could mean a few different things, I feel as though it could be your body traveling from one dimension to another. The reason that the sound is glass breaking could be due to the fact that you are so aware of it.

I agree with JB that you should not completely allow yourself to go until you feel you are safe, because you should always trust intuition. Do not lose hope in these vivid dreams or in your abilities.
