It could mean anything, but the most famous meaning of it is that the word “sleep” means death and “miles” means journey.
I love tattoos. And mine symbolise who I really am. I have a Samurai on my left arm. At a subconscious level, I connect to this warrior and model myself on his discipline, skills and honour. There is also a tribal tattoo and a Chinese symbol of faith. I have seen a lot of people getting tattoos just because it's a trend.
Tattoos, for me, are like a timeline of my life. I could look at a certain tattoo, and it reminds of me of a certain time in my life and why I got that tattoo.
