By using your imagination.
You may be one of the many individuals that sense the paranormal a lot more than others. You probably see, hear, and feel spirits because of your "sixth sense".
Supposedly it is the case in the TV show "Ghost Whisperer" but it could be true if you believe in ghosts and spirits. No. Babies cannot see imaginary things unless they suffer from mental illness. "Ghost Whisperer" is a fictional television show, not a documentary.
If you only see spirits during dreams while you are asleep, this is normal. The fact that your dreams frequently involve spirits probably means that you are deeply religious or hold spiritual beliefs.If you feel that you see spirits during waking hours, this could be a problem, especially if you also hear voices. This can be a sign of mild schizophrenia, a disease treatable with medication.
My real life job is to hunt ghost, spirits, and demons. I talk to, hear, and see them. I am sure they sure real.
A simple answer is no. But If you are spiritually aware (going to a spiritualist church helps you to develop these skills) or are naturally clairvoyant, you can see shadows. Then you may hear voices. Then as your skills develop, you will become sensitive to the presence of spirits.
There is no evidence to confirm nor refute the claim that infants see spirits.
A voodoo weirdo.
No.
Are you talking about the song "do you see what i see"
Ghosts cant see or tell if you are in the same room with them, unlike Spirits who can see and interact with you, you may feel a sudden cold spell as it passes you. it also may become attached to you if you remind it of someone, but I'm not totally sure we can see tham, only hear them. This is false for ghosts and spirits are the same. Ghosts decide whtther you hear them or not. It also depends how attuned you are to the spirit world.
why are you able to hear an see
You can see, smell, hear and sometimes feel them around you. Pay attention to the little things and you may see what you're looking for. They tend to come to you in just falling asleep and/or just upon awakening. Pay attention!
