The Dream Magic Experiment

I was in a house. Traveling, and looking for something. Or I was going to an alternate dimension. A person. We're searching for something. I need to avoid people.

I traveled around the house/area. I can see the alternate dimension, and the other person can also sense me. I tried to go to a room where I believed he wouldn't be able to access its version in the alternate dimension.

I walked around, and found a lot of greenery. I was in a mansion, or a hotel. Outside, it was green everywhere due to the earth-hugging leafy plants, as well as huge trees. I saw rabbits and small animals.
