That sounds exactly like meeting and connecting with a spirit guide. In shamanism they're referred to as Power Animals for the ability to give energetic power to their human, be it in the form of healing, spiritual insight, or an enhanced sense. Many shamans have been considered shapeshifters based on their habit of spiritually merging with an animal like this. In your case, you were being given a refined sense of sight. It's no secret that birds of prey have sharp sight, and it's a logical gift for them to share. In a handful of Native tribal beliefs, Eagle is considered the form that Great Spirit (God) takes, and often that eagle is specifically a Golden Eagle. One of the spirits I often commune with is a Golden Eagle as well, and she's a very reliable, potent spirit with a protective energy, so it's a very good thing that you're having one reach out to you. Just sit back and relax, you're being shown something that will help you. Continuing to watch videos of them and listen to their cries is a great way to reach out to them: observe their actions and life and see if you can get an idea of what they're trying to show you through example. It's entirely possible (and rather likely given the specific experience you had) that you're being called to shamanism
"Sometimes you will act as an angel to someone else, perhaps without even knowing it. One day someone comes up to you and says, "You saved my life." You look at her astonished, trying to remember when you even saw the person before, the meeting meant so little to you at the time. "Don't you remember? I was standing on the bridge, staring at the water, and you passed and said, 'Good morning'."
