well it really depends on the dose theres a scale lets call it the trip factor going from 1-5.
(this isnt the actual scale just my interpretation)
level 1: slightly happy feeling, time seems to slow down slightly your thought patterns may become more fluid yet strange
level 2: time expands further, an extra awareness of your surroundings may open up, slight (mostly social) anxiety may start to raise its head here, things may look as if they are shifting or warping very slightly without actually moving, strange thought patterns will increase
level 3: still aware of your surroundings but things will be very unreal, patterns may appear to move over objects, colours will appear much brighter. very confusing thought patterns will take place now mostly things will seem pretty funny though, social anxiety can be quite strong now or you may be laughing too much to notice that
level 4: very intense visuals, many colours appearing and moving on surfaces patterns will appear and move around and over objects, things such as doors and windows may appear to be open although you can see they are not. train of thought will be pretty much uncontrollable and confusing (or funny depending on which way you take it), moving may feel very strange, as if you are not moving through your surroundings but rather they are moving around you. deep life changing thoughts and realisations may enter your head, epiphanies
level 5: complete loss of awareness, ego death and meetings with entities.
