Nobody can really recommend you a psychedelic experience because each person is unique and each experience is unique, but you should definitively research a bit before trying it. Erowid is a good resource to learn more about psychedelic substances.
Some common advices: be with people you can trust, in a non-harsh environment, and don't try it if you are tired or going through hard times. You could also start with a very small dose the first time to have a grasp of it (although it's difficult to measure dosage with mushrooms, but you could try a small amount of dried mushrooms which are less psychoactive).
My experiences with mushrooms were great, but not really life changing or anything like that, just pretty interesting, fun, and maybe even artistically inspiring. The only substance that have had a real impact on me was (tested pure) MDMA: I only did it one time many years ago, but it helped me understand the value and significance of interpersonal interaction, which I believe made an important positive effect on me.
