Most interesting place to find this type of post, but nonetheless here it is. Are you looking for a companion, Guide, or an actual Guardian? A Dragon Companion would only be of use if you practiced Dragon Magick. A Dragon spiritual Guide would make sense if you practiced Shamanism. And if you had a Dragon Guardian, I would think he/she would make their presence known to you in due time.
While you ponder all this, I would suggest that you work on meditation, and opening your Third Eye, and also working on all of your Chakras.
