The more formal wording is Paranormal Investigator.
Okay so you are curious about all this spirit stuff? You want to know what’s out there waiting to be discovered and how you can contribute. That’s cool, an extreme curiosity is key to happiness within this work. Get yourself a snap camera and temperature gun for shooting temperatures. Have a pure consciousness, be open minded, and keep the bar low for results.
Next, get permission to walk around a home or warehouse. Keep the lights on or off it is your call. Spirits are spirits, they are present during the day or night and cannot tell time. If you want to get your freak on, you will definitely want to walk around in the dark. You will need a torch or flashlight so you can be sure to blind your partner that you convinced to do this with. LOL. Adding a red filter to your light will help everyone from being blinded and preserve night vision.
Finally do not smoke or wear perfume/cologne while investigating. You will need all your senses to be pure in order to discover odd odors. It is important to journal everything. Above all, always be professional. This will help you gain a positive reputation and possibly lead to others requesting your assistance. If you happen to see a spirit enjoy your time with it, remember it is just another human looking for the same thing you are seeking …CONTACT.
