Well, that's pretty much subjective I think. I personally feel that mushrooms create that feeling much more than LSD does, but you have experience with those too so one can't say for sure. But since you have experience with a wide range of psychedelics, I have to assume that you know effects well enough to differentiate between compounds that are visually similar. My suggestion would be, if you really want to be sure, how about trying a high enough dose of morning glories or hawaiian baby woodrose and seeing if they are similar enough to what you had? They are the only other psychedelics you'll be able to get ahold of in the same family of chemicals, after all.
