To the OP:
I used to do the same type of meditation. Candles are great for putting you into a trance!
I believe what you heard was two guides that were very excited that you finally got through. We all have spirit guides, usually several depending on
what and where we are in life.
When a person begins to be able to lift the curtain between worlds, at first things become very strange and scary. It is how we evolve spiritually if
this is the road we walk.
Once these doors open, and the connections become clearer, it is not nearly as scary, and you might find it feels natural and almost like something
you are meant to do when you begin to communicate with your guides.
Eventually this doorway leads to becoming a medium.
Know that opening these doors will freak you out, and possibly delay your spiritual advancement out of fear,but the doors must open, and in the end,
there is nothing to fear, it will instill a sense of honor and amazement, as you work side by side with spirit....
Best of luck on your journey!
