Can a Jew contact a departed person? If so, are there laws governing this action? If it is possible to contact the departed, if the G-dly soul returns to the Creator (baruch hashem) after a person dies, how then is it possible to make that contact? Does the soul have a memory?

Attempting to contact the dead is strictly forbidden (see Deuteronomy-“Devarim” 18,11). Anyone who acts in an attempt to have the dead contact him is in violation of this Torah prohibition (Rambam Hilchot Avodat Kochavim 11, 13). Jews have better things to do and therefore do not waste their time on this kind of nonsense (see Rambam Hilchot Avodat Kochavim 11,16).
