NOS makes you just kinda sit and watch the room look like its repeating onto itself, and it's a very funny experience. The sounds you hear also echo over and over, to match the visuals. You disassociate from the world around you for but a moment, but you know you are on something, and it lasts like less than 3 minutes. Again, all of it is hilarious. You will say words just to hear it echo in your head. It doesn't actually make you see things like trees, and you aren't in a state of mind to go running around and stuff. There is a difference between a hallucination like seeing a forest and monsters (like a nightmare or a bad mushroom or acid trip or dmt) and then just visual hallucinations like things looking like they're melting (like a light mushroom or acid trip) or repeating themselves (like NOS or salvia). In this particular situation, I don't think 'laughing gas' is the solution you're looking for.
