There is no good reason to believe that "ghost hunters" encounter or detect anything paranormal. Their equipment can be triggered by many different things in the environment including power lines, cell phones, or radio towers. Their audio recordings often sound nothing like what they claim to hear, and saying you feel spooky sensations proves nothing to the person at home. Ghost-hunters go into their investigations biased—expecting to encounter ghosts—and their entertainment-driven shows are incentivized to exaggerate or outright lie to viewers. Many characteristics of "haunted houses" in fact have very straightforward, naturalistic explanations.
