I like your page, I found it by searching for Bunyip, I was really scared by it.
One thing that most scared and affected me was the movie "Jumanji", which is actually a good movie and I liked it, but there is that scene where this gigantic plant grows and attacks people. I am still scared by it, so everytime I see that movie I start having nightmares about big human eating plants. That said, I still have problems looking at flesh eating plants or at unusually big plants, also afraid to touch them. When I am in the bathtub, I sometimes have got day nightmares, that out of the sink there might come a big plant and eat me...
That is still scaring me.
