I have had some experiences with psychedelics and I would say to you that it is not necessary for you to rush or even want these things. All of my trips involving psychedelics were "random". They called on me unexpectedly for me. However, these substances are just tools to show you what you can achieve if you practise enough meditation or use other techniques like hemi-sync. Maybe the visualizations aren't a lot truthful but your senses get to a new level and that in my case is real. It is possible to achieve it without psychedelics, they are just tools to help you shorten the time period needed by getting your mind familiar with what it can achieve and faster its learning capabilities. Take your time, if it is meant it will happen.
