Am i a "psychic"???????

im a 15 year old guy ever since a couple years ago ive seen or heard people in my my house that i know are not there like heavy boots walking or like a guy in a blazer it happens for a second and i do a double take and its gone and whenever i randomly guess something its usually 100% accurate like in math ill blindly guess and its right and i took a math test charting my skills in different categories and i was average in all of then but really high in estimation coincidence?? its got me thinking
