spooky.... and yes, don't ever reply to whoever call you from behind in the jungle... my dad used to work in the woods...
as for the hysteria part... when I was in UTM Skudai, first year all of us had to stay inside the campus... and weird thing was we would hear girls screamed hysterically some nights... (I stayed in the all girls dorms, we called them kolej, the one and only all girls dorms in UTM, Kolej Tun Fatimah).. And the seniors would tell us "ghost stories"... =_=|||
