Bp 120/135. Shortnes of breath. Complete numbnes of left arm. Tingling in my extremities. Dreaming sensation. Disoriented. But all symptoms lasted?

120/?? Not sure what your BP is since 120/135 is impossible. Tingling, dreamy feeling disorientation suggests hyperventilation but a toxic drug exposure could do it too. Numbness of the left arm, if brief, is most likely a compression neuropathy - so long as it resolves with movement. These are my immediate thoughts - if persistent, see your doctor.
