The spiritual 4th dimension is not only a peaceful place. There is war going on between good and evil spirits. The laws of attraction especially work very well in the 4th dimension, much more than they do in the 3rd dimension. In fact the laws of attraction work in our 3 dimensional realm only because events in the spiritual 4th dimension influence our 3 dimensional realm. According to this law of attraction good thoughts attract other good thoughts and spirits which causes a positive spiral. Therefore there is closeness of good spirits and distance between good and evil spirits. Evil thoughts attract other evil thoughts and cause a negative spiral. Some thoughts in the spiritual 4th dimension are very powerful and appear as images within the spiritual world. Therefore some would call the closeness of good spirits who cause a positive spiral heaven and the closeness of evil spirits who cause a negative spiral hell. You can experience hell already as a human on planet earth if you continuously concentrate your thoughts around negative emotions and evil deeds. After death you can easily bring your soul to closeness with other evil spirits according to these laws of attraction. In addition I believe there are certain good spirits like an archangel for example who dedicate their existance into guiding your spirit to a place where a maximum of closeness of good spirits exist and where that closeness helps to do a projection with images of a nice place that these spirits love to call their home (heaven). It is all about the vibration in the right frequencies and according to David R. Hawkins you cannot enter certain consciousness levels (frequencies) - like heaven - as long as you are blocked by your negative thoughts and emotions. I hope that helps you how to think about heaven and hell. This is the best explanation I can give you from my own experience with the 4th dimension and how to think about the spiritual realms.
