Lots of good thoughts in here, there are many ways to work with this experience I think. I have discovered a few basic ideas pertaining to the mind that may be useful to you.
First, only that which you WILL is YOUR SELF. This is an idea which relates to the origin of thoughts. Speak something in your mind like "This is my Voice." Then you have thus found your voice. If you will it, it is yours. I know the idea of 'everything is yourself' is a popular one but I think its more along the lines of 'you are yourself and everything is a reflection of that'. A subtle but significant difference in my mind.
Second, EVERYTHING ELSE is a CREATION. The mind creates an experience of the communications between intelligent energies. You are likely empathic and have opened up too many lines of communication which has crested many a disjointed conversation. Thus, with YOUR Voice you may adjust these channels. If you hear it without willing it, it is a communication.
There is a process I have found effective for myself. Anytime I hear a voice that is not my own willed voice I ask it - Who's voice is this? I ask it over and over to the voice while seeking to know its identity with my intention and will. Sometimes it merely vanishes and I know it was a voice all in my head. Other times I will discover or have some chain of thoughts that will connect it to some person or thing (such as the tree you mention) and then I assess what the state of the relationship is. More often than not we are plugged in to too many people that we don't need to be so you may need to go through each voice and connection and determine if they are healthy for your field. If you need to sever a thread you will visualize yourself and whatever you are connected to each as s field with a thread of light between you. You then 'slice' through the thread and allow each end to retract. You may need to do his several times or over a period to get it to stick, especially if the person is emotionally or energetically focused on you in some way.
However in cases of positive interaction such as with your tree friend you are experiencing one of the positive benefits of indigo interaction being telepathy with other fields. I would highly recommend speaking with the tree more, they are wise beings, but can also be limited and crafty so keep on your toes and don't believe everything you hear. Just as a word of general caution, not of fear.
