Dear Daniel

After studying your dream, there are many aspects of the dream that I must interpret for you to understand. Firstly, the Charm Symbol Tattoo - a charm is a less serious version of a talisman and yet used to acheive the same result - to protect the wearer against bad luck. Yet when one dreams of a charm / talisman it is indicating that you may be lacking self confidence and feel the need for external assurance.
The fact that your best friend is wearing a charm tattoo symbol in the dream, is showing that he is making a statement through the artistic impression. A tatoo in a dream whether on your body or someone elses' holds significance. Do you feel that your friend has a better lifestyle than you at present?

Secondly, the fact that your friend suddenly started to strangle you many suggest that although you may have tremendous time for your friend, you may sometimes feel stifled by him.
When we drean about being strangled we are generally conscious while this is occuring in our dream. The dream is telling you to become more assertive and take control of the situation in hand.

Finally, the fact that an invisible force pulled you apart may show you again that although you have a strong friendship, you may both need to allow some space so that the friendship may continue on a healthy level and not result in annoying each other or falling out. Remember the best of friendships need space.
