What defines weightlessness feeling during a fall?

So I know that we feel weightless during a free fall as there's no normal force acting on us or my other way of thinking is that considering a lift and both lift and I fall with $g$ then no normal force between us to make me feel my weight and if lift is accelerating up then I will feel my weight more as I am experiencing more normal force from lift. Now what if I am moving with upward velocity and gravity pulling us down, I should still feel weightless it just I am moving away from lift and still no contact so I will still feel weightless. So even if I have more acceleration than $g$ and have no contact with any surface means experiencing no normal force I should feel weightless? So I have a doubt in a question of simple harmonic motion. A man of mass 60 kg is standing on a platform which is executing simple harmonic motion in a vertical plane. The displacement from the main position where is his $y = 0.5 sin(2πxt)$ . The minimum value of $x$ for which the man will feel weightlessness at highest point The answer suggest that at highest point it will be the extreme point of simple harmonic motion so at highest point there will be maximum acceleration which will be equal to w²A(absolute value)(here w is angular frequency and A amplitude) So w²a= g (they put the values and got the answer) But I think that value of x doesn't matter as long as we don't experience a normal force Correct me if I am thinking wrong.
