LSD feels electric and strange and odd. If you are in a good mood it will be great or with friends. Loads of creative thoughts. Merging of all 5 senses. You can see sounds, for example. Physical reality morphs and changes in high doses.
In my opinion, it is best to test out the waters, with half a tab or 1 tab rather than going into a high dose. If you have done DMT then should be no issue for you. But I'm guessing it is probably different. Like LSD is definitely different from shrooms, which went against my expectations.
