yes, Shamans have been doing the vision quests into animal bodies for thousands of years, You have to wait for the animal to invite you in. I do mine with no substances or drugs.

Ive been in a bear and a wolf body. The bear had incredible sense of smell. I later learned they are more keen than a bloodhound.

And coming out of the wolf. I craved raw meat, I went to buy myself a steak and cooked it rare .

With insects, I cant do it with a squashed body, and it takes a great deal of energy, Only been able to do it three times.
