Strange Output from Image/Container?

Hello, I am fairly new to Docker and am trying to run an image and when I do I would usually get “inside” the image if that makes sense, where i can access different directories that i have made inside.

However, when I have done it recently I have gotten the following output:

top - 15:49:10 up 2:36, 0 users, load average: 0.65, 0.70, 0.71

from the following docker command: sudo docker run -i -t ubuntu-latest

I am running docker 17.12 on ubuntu 16.04. At this time If I could receive a solution without having to post the dockerfile I will, due to certain information being present in the file.

Any feedback would be greatly appreciated
