De Broigle's equation for "matter wave" and slowing down an object

I was reading the wave-particle duality and there are is something I don't understand:

Can you slow down an object enough for it to start behaving as a wave ?

ej: let's say I weight 81 kg and I want to behave as a wave of λ = 600nm(yellow light) then according to De Broigle's equation :
v = h / mλ
v = (6.626068 * 10^-34) / (81 * 6.0 * 10^-7) = 1.36338848 × 10-29 m/ s

Now, is this possible ? does the velocity have to be absolute or can I have wave behaviour for a given frame of reference?

Meaning, let's say I start running from rest until I reach a velocity of 8 km/h, then, there was a point in time where I had to have the required velocity to behave as a wave for the given λ, at least to the observers that were on my same frame of reference.

Or does it have to be absolute ?

Meaning, I have to take into account the velocity of my planet as it goes around the sun, plus the solar system as it goes around the center of the galaxy, and the galaxy as it moves towards some point in the universe.

Do such places exist, where the velocity of an object is so slow that I could behave as a wave ?

Although if you want to try to cool yourself down to 10^-58 Kelvin to see if you turn into a wave, don't let me stop you! You might even discover something cool along the way. Let us know how it goes ;-)
