I think psychedelics can help us pierce the veil of this reality, and while I don't pretend to know exactly what happens while on them, I suspect they are altering the frequency at which we perceive this reality, which is why we see geometric patterns and lines of interference when tripping - it is how this reality is constructed (in my view).

Lasers are unique because they are point source energy, which are very different from regular light (compare the danger of a 5w laser and a 5w light bulb). I think one needs to delve deeper into what light is to begin to better understand how it all comes together.

We all make the same observations, but the conclusions drawn in the mainstream are, in my opinion, not correct in the slightest.

It all comes back to energy, frequency and vibration.
