Living in a dorm is tough, especially when you're coming from living in your own room. It's hard to make your room feel like your own but here are a view ways to help.
Bedding:
Buy a nice comforter or duvet cover because you're going to be seeing a lot of your bed. Maybe even splurge on some nice statement pillows.
Pictures:
Lots and lots of pictures. Of your family, friends, dog, cat, favorite place back home, anything that makes you smile when you look at it.
Food:
This one is pretty fun. Sometimes, it's nice to bring your favorite candy or snack and keep it in a special place so when you're feeling homesick you can grab it and eat!
Signs:
A lot of people like to have quotes or small signs around their room that remind them of home. I have a pillow that has my zip code on it which I made with my best friend, and I love it because reminds me of her and my home!
Scents:
Because you can't have candles in most dorms, it's nice to buy an air freshener with a nice scent to make the room smell good when you walk in
It's important to do things in your room that make you feel relaxed and at home when you're there because you're going to be spending a lot of time doing work, eating and of course sleeping in your room. Make it a place that feels like home for you to go back to.
