some of the people i know have told me that the feeling that you get through out your body when on DMT is the same way your body feels when on LSD..?..?..?..
They are very different. LSD lasts like 7 hours, where DMT lasts like 7 minutes. With LSD, you can easily walk around and me pretty much functional. With DMT, you're not moving anywhere.
how you "feel" on psychedelics is totally subjective, and varies with the same drug in the same person at different times, let alone different people and different drugs. psychedelics are not simple take em and have a great time drugs like mdma, please seriously consider what you are planning to do.
Both are very different, like someone else said even with the same compound youll have different experiences due to different set and setting, people around you, etc. also experiences vary theres always something different and new for me, why I never get the thought that iv seen everything.
Also you could look at erowid for more detailed information on dmt and lsd.
Your question is too broad. Do some basic research on Erowid by reading the overviews for each drug, as well as a number of trip reports, both good and bad. Then come back here if you're still unsure about something specific.
LSD and DMT are like an automobile and an airplane. They only thing they have in common is that they can both take you for a trip.
