Yes - Gurbani supports the view that there are ghosts.
ਜਿਤੁ ਦਿਨਿ ਦੇਹ ਬਿਨਸਸੀ ਤਿਤੁ ਵੇਲੈ ਕਹਸਨਿ ਪ੍ਰੇਤੁ ॥
On that day when the body perishes-at that time, she becomes a ghost.
ਪਸੁ ਪ੍ਰੇਤ ਮੁਘਦ ਪਾਥਰ ਕਉ ਤਾਰੈ ॥
Even beasts, ghosts and the stone-hearted are saved.
ਕਈ ਕੋਟਿ ਭੂਤ ਪ੍ਰੇਤ ਸੂਕਰ ਮ੍ਰਿਗਾਚ ॥
Many millions are the evil-nature spirits, ghosts, pigs and tigers.

it just says "pathar"....meaning STONE (S)...where did the hearted come from ?? Added by the translator !!
IF the word "hearted" is accepted with the word STONE....then the SAME should apply to the preceeding words.... Then Pashu - Animal becomes..Person with animal birtees..animal like....greedy /lobhi like DOG..Sex Crazy..like the Elephant...etc etc..and those with "Ghost" like birtees... Its a FACT that there are LIVING HUMANS with...Animal Instints ruling them....also humans with Ghost instincts..and YES humans with hearts of Stone....AND
YES>>ALL THESE HUMANS CAN BE SAVED !!!the bottom line is HUMANS.....MANUKH SREER.....not stones, not animals..not ghosts....
GURBANI is FOR LIVING HUMANS !!!
The Translator has LEFT the Bhoot pret animal etc alone and when he came to the STONE...he...decided that an "inanimate object like STONE..which has NO LIFE..couldnt be REBORN....so he looked around and settled on.."stone-
HEARTED !!" he twisted the Gurbani to FIT ????
2. Scientists are even NOW "DISCOVERING".....that STONES are NOT INANIMATE after all...Many Life Forms in the Forms of CRYSTALS...stones etc..come to LIFE after being submerged in water..a "seemingly stone" dead object..is actually a LIVING THING....
Its NOT said in Vain..Gurbani is AGAADH BODH..too deep and too advanced for our simple "translations"....we just cannot twist it to FIT our feeble jigsaw puzzle...
