I wonder if there was a collision of super heavy black holes, would we feel the gravitational waves by ourselves

  If you're close enough to feel gravitational waves, it's unlikely for humans (or even planets) to survive intact.

  I don't think so, or as someone else pointed out, it would rip the earth apart before we felt it. I'm no physicist, but, the earth is massive so is influenced a lot more by external gravity than the specs on its surface that are people. Take the moon, it's a huge object hovering over the planet (effectively, it's slow moving, the earth rotates underneath it), its gravity pulling on seawater and causing ebb and flow. But we cannot feel its gravitational effects ourselves.

  Colliding super heavy black holes wouldn't do it. For us to feel a gravitational wave, it's wavelength would have to be small compared to a human body, which in turn means the pair of bodies emmitting those gravitational waves would have to be separated by at most a few meters, but supermassive black holes would merge long before they got to that point. Indeed a pair of bodies capable of producing gravitational waves with both the frequency and the amplitude probably can't physically exist. One could imagine though some configuration of many pairs of black holes, orbiting at different frequencies to interfere with one another and produce a sharp beat, perhaps with other mass configured to act as focusing lenses. Still almost certainly wouldn't exist in nature but a cool potential scifi concept.
