Its probably nothing, but this is just something that Ive unintentionally experienced, which isnt something Ive really done, and Id like some opinions.
A couple months back, I had a couple of strange dreams in a row. One that I remember was an odd one. I was in a bathroom that looks like the one in my home, but just more lush, it was cleaner, had a bigger mirror, better counters and so on. I stared in the mirror, and saw a short boy staring, probably 7-10 and looked of Indian descent. As if some trigger went off, I realized it was a dream, and achieved lucidity for the first time. One of the fatal flaws for my dreams was that the person I was in the dream was aware that it was a dream, making it harder for me to realize that I could take control. The room went to how it was in my house, but the control just slipped. Im not sure how, it was like I just had too much power and couldnt hold on. The bathroom reverted back to the better one, and the door opened. Still looking in the mirror, I saw a wave of darkness just swallow me, or him, or whatever you would say.
Now, that dream stuck with for a while, but it was when I saw the same person again it startled me. Not in real life, though. I was trying to fall asleep, far more recently, and fell into a meditative state. It was the location of a previous meditation I had done. I was on a small path seperating a small forest with a beach beyond it and lots of grain that was being farmed. I saw the same boy, walking down the path with a tiger. I brought myself out of the meditative state immediately.
I'd go with possibly a past life, or possibly even tutoring like spirits trying to tell you something, or pass on a message to you. I'd do more research on the meanings of tigers, and maybe events in areas something like this could have happened.
