Hm...
Computers do give off EMF. And EMF has some role in the paranormal. Now, the question is, does the EMF from a computer actually enhance ESP and other paranormal powers, or does it simply cause one to have hallucinations to make one believe such things are occurring? Ghosts, spirits, and other paranormal entities might use the available EMF from the computer as a power source, or the EMF may trigger parts of the brain to make one more susceptible to such things (including clairvoyance and other forms of ESP), or it may simply trigger parts of the brain that make you think you have become more clairvoyant.
EMF is thought to cause strange feelings, feelings of paranoia (like feeling as if you are being watched), and perhaps even hallucinations. So it is hard to say for sure. Could be, but there could be other possibilities as well.
