The only way?

Is our existence the only way to perceive the universe??
We perceive our environment with all our sensors (eyes ears asf), but I wonder if there´s another way to perceive.
Our does it come as a package: like a key and it´s lock? So our environment and us just are counterparts of a (superiour) unknown thing; and there might be more packages, more locks and keys, or even packages of a totally different kind.

My questions didn´t get an answer, but it rose even more questions....
