I tried puting the melody of the Poltergeist Theme onto guitar and it sounds good,im too 
to put it sorry =(
to put the rythm and everything so just listen to the soundtrack and it'll work and so
it is:

|-----5p0----5-5-3-6-------3--------|-----5---5-5-3-6--------3-------|--------|
|---6----------------3-5-5---3-5----|---6--5----------3--5-5---3-5-6-|--------|
|-5------------------------------5--|-5------------------------------|--------|
|-----------------------------------|--------------------------------|--------|
|-----------------------------------|--------------------------------|--------|
|-----------------------------------|--------------------------------|--------|

( I kind of rushed into this part and it might not be very natural to play it like that, 
you got suggestion tell me )

|-5-8-10---5-8-10---8-5-8---5-6--|-3-5-6---3-5-6--3-5------|
|--------------------------------|-------------------------|

|-5-8-10---5-8-10---8-5-8---5-6--|-3-5-6---3-5-6--0-1------|
