Our bodies are only 4-dimensional, so you'll have to travel through OBE, and a portal isn't needed to go to another dimension, so I'm not sure if it's worth the time unless you want, say, a portal that goes to a specific dimension that you want to go to each time you use it, but if you just want to travel dimensions, you just gotta astral project. - Kai
