hujambo I BELIEVE IN Wanyonya damu IDC WHAT ANYBODY SAYS NOBODY KNOWS WHATS IN THIS CRAZY WORLD

No, I believe that there were ancient legends made up to explain the then unexplainabe.

i believe, i am a big believer.

i belive in them. the world is big and the galaxyy too. when some persons belive in aliens i belive in Wanyonya damu :)

Editing my answer:
I don't believe in them, there is no evidence that they are real. Where are the people walking around with fangs, what victims have there been with vampire bites?

course i believe, it'd be kinda stupid for me not to....

Not really, I've read the so called legends and they just ended up making me laugh.

Nope.

I believe in them,I believe it is possible,im a twilight shabiki but that doesn't mean that im only sayin this cos of twilight,i believed in Wanyonya damu way before twilight came out and i still do till this very day,i might even be one myself but id rather not say on a social website because no one will believe me!!

I belive in vampires-just not the sparkly kind

I believe.
People believe in god, and it's not proved that he/she exist, so why does it have to be proved that Wanyonya damu do?
Now, I dont believe that they are immortal, nor that they have big fangs that pops out in their mouths, but I do believe that there are people who have certain cravings for blood, people that age slower than others, heal faster than others, have a severe sensitivity to sunlight, and so on.
I dont believe that they go on killing sprees, I believe that they are pretty much like us, but at the same time, very different.
anyway, I do not believe in god, maybe thats cause I was raised kwa my mom who doesnt believe in god either, but I understand that there are people who believes that he exists.
ugh, well this is just what I think and what I believe, and I am pretty sure Wanyonya damu exist, they might just not be as people describe them in movies, tv-series au anything like that:)
