Hi. The kitchen is the heart of the home and the most important room in the home, its where everything happens. Do you feel safe there and at ease? Or frightened? Try smudging and hanging some light catchers in the window and place lavender in there. Do a little research on kitchens and you will see it is the best room in the home! You may have some sort of portal or maybe a playfull spirit but this wouldn't be because its the 'kitchen' it just so happens your kitchen was built over it... I don't really hav any advice on what you could do with portals ect but if it is a spirit and you don't like it the just politly ask it to leave as it is frighening you, it will so make sure you really want it to first if that is what it is!. It works for me!

Peace
