5D is not necessarily a better place than 3D
Law of pattern, law of attraction, law of correspondence, law of resonance, law of karma, law of magnetism - these laws and energies will find us whether in 5D, 12D or 3D.
Heaven can be on Earth and perhaps even 2D.
Hell can be in higher dimensions and within the body.
If you don't enjoy what you are attracting on a daily basis, change your energetic pattern.
