It would help if you provided some sort of reference or link, so that those of us who have no clue what the heck you're talking about could respond in some manner.
I've never heard of this...whatever it is. So I cannot believe or disbelieve in something I've never even heard of.
I should like to see some reference to this.
EDIT:Because I was too impatient to wait for you to respond to this, I did a little of my own research. And I've come to the only conclusion an intelligent, rational person can come to (as supported by the references below): any mythological construct, fabricated in very recent years by someone on the internet, is patently-ridiculous. And since the internet can spread a thing like this faster than the proverbial wildfire, any number of people can get in "on the fun" and make all kinds of outlandish claims just to get attention or to engage in "mob rules" thinking (go with the crowd). The point? It's a load of horse puckey. It's not even a legitimate mythological construct of the distant past from any culture. It's an internet creation. And obviously not even a very popular one if it's not something that instantly springs to mind once the name comes up in a forum topic (to wit: I'm on the internet a lot, and I've never heard of this until stumbling across this topic...because I do actually spend the greater balance of my free time outside in the real world rather than lurking around vague or disturbing internet forums like "Something Awful" or wrapped up in video games).
Cryptozoology is for crackpots...keep that in mind.

I found these references on the internet, which debunk the entire notion:

This guy's statement on this webpage ended unfinished. Perhaps he simply forgot to add the full stop (period). Perhaps he can't edit his own material worth a dang. His other material on his site makes me believe he's a bit of a cornball, especially buying into this "tulpa" nonsense. But whatever...
"Any sightings before the entry in Something Awful has to be fake, as the concept of Slenderman was invented in that thread. However, although many people have said since he appeared in a competition he must be fake, I (C-Man121) do not believe this to be true. Although it is highly unlikely the Slenderman is real, it is possibly he came about due to the Tulpa Effect. If the Tulpa Effect is possible, then in theory"(
