This is a Pulse-inspired website that is v-e-r-y well done. In Pulse, people see dead people... Evil spreads through the computers and radio waves to take the place of the living, leaving only a few - hence the sequels that were announced not too long ago.
quieroverunfantasma.com plays uses the Pulse themes and some of the footage, but the site puts an original twist, and it somewhat creepy. Mission accomplished.
